Niggling Problems

[chrislloydie]

Got a few niggling problems. Thought I'd post them all together rather than individually. Any help would be most appreciated.

2002 1.9tdi (pd) auto. 142k miles.

 

1. Got a loud induction type roar when accelerating. Removed and refiitted airbox and still there. I've checked the ducting on inner wing and it's ok. Any other obvious suggestions? The roar is not really audible from outside the car but is loud from inside.

 

2. I get a kind of chirping sound from front passenger cabin area which is heating blower related. Fans on low or highest setting, no noise. All other settings results in the chirping noise.

 

3. Centre dash chubby hole struggles to open. Have to bang it yo open it. Any tips?

 

4. Headlight adjustment wheel doesn't work. The wheel spins freely. Should it have like a clicking resistance to it when turned?

 

5. The engine is using about 400mls of oil every 2k miles approx. Is it normal for the pd engines to use a small amount of oil.?

 

Thanks guys.

Also, noticed in the colder weather it idles very lumpy and noisily for a few seconds. A couple of times it died after a second and I had to restart it and use some revs for a few seconds until it settled down.

The heater blower noise is coming from the back right of the engine bay as you look at it. It's a bit intermittent so hard to pin down.

[chrislloydie]

No-one help me with any of these problems?

I'm not sure about your gal but my mk1 the blower filter (cabin) is on the back right so if there is a problem with your fan matrix then the sound could come out there.

 

The oil it is reccomended you check level every 600 mile (according to handbook) so off that i assume the car would use a little bit or lots depending on how well it's been looked after from new.

 

The cubby hole in the dash may need removed and cleaned and oiled (wd40).

 

The head light has two main bits inside and outside the inside will have a knuckle where the headlight adjuster sits this may have come out or been broken so it won't adjust usually after a bumpthe only thing i can suggest is to take the light off and check it may just need popping back in.

 

usually the induction type roar is from a performance filter (k&n that sort of thing) or incorrectly fitted standard filter

[chrislloydie]

Cheers for the reply mate. I'll have a look at those things over the weekend.

 

Re the roar noise, I've got a standard filter fitted. I've removed and refitted and no improvement. The performance is funeral. It's just the awful bloody noise.

[chrislloydie]

Performance is fine, not funeral. Bloody predictive text.

just a thought is the pipe that leads to the air box from the grill ok can't think of owt else

[SilverBeast]

Sounds like it's possibly loosing boost. If it was bad enough it would be seen as underboost (lower boost pressure than expected) and cause the engine to go into limp mode.

I had a pipe between the intercooler and the inlet manifold I hadn't fitted properly once and it was practically undriveable as it was shunting a lot. Try checking pipework between the turbo and the intercooler and the intercooler an the inlet manifold. (Second one first as it's easier). On mine there is a fitting from the intercooler outlet to the hose that runs to the inlet manifold that is held on by two screws. I have just tightened this up (OK put a two match sticks in to tighten the screw in the hole) as it was loose as the monkeys that replaced the radiator last year managed to strip at least one of the threads (amongst many other things). It wasn't too bad but I believe some boost pressure was being lost out of this joint.

 

I would guess that leaking air from the presurised pipes after the turbo would also make a roaring noise if air is escaping, possibly similar to the induction roar you describe. The hose from the intercooler to the inlet manifold passes to the top right of the cylinder head as you look at the engine.

[chrislloydie]

Cheers guys.

 

I have no pipe from the front grill to the airbox. I have the pipe in the inner wing that runs from the airfilter box at one end, the other end finishes under the front drivers side headlight unit which i did think was an odd place to draw air from. Am I missing a piece of pipe from there to the front grill?

[SilverBeast]

Mine just ends under the headlight as well, heres a picture with the headlight out

 

 

I have previously asked on the Forums if there is something missing from the air intake ducting but the consensus seems to be that there isn't. Though there does appear to be a piece missing right at the front just behind the bumper.

 

It may be worth checking that the pipe in the wing that goes from the intake under the headlight to the air filter box are attached properly. Mine wasn't fitted correctly (same monkeys when they did the radiator) and I only discovered that because I needed to change one of the bulbs, and it's easier to do by taking out the headlight. You can see it quite clearly at the left hand side of the picture.

[chrislloydie]

Yeah mine looks exactly the same as yours. The pipe in the wing on mine seems to be attached properly. But looking at your picture closely, it does look like there should be a further piece of ducting.

 

Was hoping that this missing bit would be the answer to my loud roaring noise.

Chris,

I've got a 53 plate Alhambra tdi 115 manual with 155k miles on the clock and some of the same probs:

 

1. "Induction" roar.

Mine has been loud from inside not out, almost tappety on acceleration from 119k miles when I bought it. But its not tappets since as soon as you take your foot off it's quiet. I've also refitted everything on the air box, ducting and no change. I suspect something is leaking on the exhaust side of things but have never managed to trace it despite feeling everywhere for hot gases and looking for sooty marks. Also I'm missing the undertray, I am wondering if there is something happening with sound reflected off the road, long shot. Also I wondered if my car is lacking some sound insulation from the pedal area. Certainly my old Audi 80 tdi made this noise with the 4" of sound insulation removed from the passenger side footwell area when it had to be taken out to dry off (long story). My Alhambra has next to no sound insulation in or above the pedal area. I might try something there if I had the time and could think of a way of preventing it slipping and jamming the brake (could be nasty). There have been so many other things to worry about fixing I doubt I'll ever get around to it though.

 

2. Chirp

Same with me. I have to take the scuttle / plenum plate out to fix the aux. heater pump so I'll take a look at the blower motor bushes / bearings and let you know, they might be dry. Sometimes phospor bronze bearings will seize to the shaft and then spin in their spring-steel mountings: hopefully over the Christmas / NY break.

 

3. Centre cubby - whenever this has happened it has been something like a pen or sat nav was jamming it and deforming the lid a little, pulling the catch out of line.

 

4. No clicks on mine, but stops rotating at either end. Neither headlamp motor works so not a problem for me, and aim seems OK to pass MOT. Oddly my older, similar mileage Arosa with similar parts has never failed.

 

5. Mine needs about half this amount of topping up between oil changes. Is it leaking at all? Mine doesn't, yet.

 

Also intermittent lumpyness/stalling on idle has always been MAF for me. It also causes snatching and kangarooing on very light acceleration. Take it out (break the pins off the 2 anti-tamper screws so you can wenge something in and turn them) and give a good squirt with carburettor cleaner, you shouldn't need to dis-assemble or touch the fragile element.

 

I got my front tyres done the other day and the mechanic showed me the 10mm front-back movement on the nearside wheel which he found when torquing up the bolts. So now there's a ball-joint job getting added to the Christmas break to-do list. So, the investigation of the roar gets put off again...

Right, I had my blower motor out today to check out the chirping. There is a post here for someone who had the same experience:

 

http://www.fordgalaxy.org.uk/ford/index.php?/topic/23816-front-fan-high-frequent-noise/page__hl__blower

 

The glove box comes out reasonably easily, you have to remove the embellisher on the left then press down the plastic catch on the right to let it drop a bit further then pull the two hinge pins out where they snap into the plastic surround.

 

After that the fan motor is behind a sound insulation moulding nearest to the door. Remove the connector by pressing the catches on either side, then there are two push-on clips holding the sound insulation moulding. Lever the two clips off then it slides back after moving parts of the loom slightly. The plastic body of the motor is then revealed. There is a small catch at the bottom. Lift this a little while rotating the whole motor body clockwise and withdraw it.

 

Mine rotated fairly freely without any odd noises, but it slows to a stop in a second or so when spinning by hand as fast as possible. The motor itself is mounted into the plastic shell on 3 rubber wedges which you can press back in turn with a small flat blade screwdriver, then it just pulls out. The brushes and commutator looked fine and had plenty of wear left. The motor does seem to be pretty impossible to disassemble much further, everything is staked or welded, and the fan looks to be pressed on. I blew the dust off and put some WD40 on the bearings to see if they would free up at all - they didn't, so I lubricated the bearings with a drip of light oil.

 

Reassembly is pretty easy but you need to lift the glove box damper so the gear engages with the rack on the moulding otherwise it will drop immediately you open it rather than glide down like it should.

 

I'm not sure yet if my chirping is fixed - it was pretty intermittent and worse when going around bends.

 

How are the rest of your niggles?

[gregers]

chirping eh,you sure its not the tensioner/pulley bouncing?.

[BigDog]

I'm sure blower fan for me, only happens with the heater blower on and defo (was?) coming from left front of cabin, not the right engine bay like when the tensioner pulley bounces, thanks all the same.

 

One more thing: an old Renault I had many years ago with persistent chirping from the blower, it turned out to be a dry leaf caught in the blades. This can't happen on a car with the pollen filter in place of course. My car has a single balancing clip like the end of a hair grip around one of the blades, this was slightlt loose and I pushed it home in case it was whistling.

 

Still not sure it's fixed.

[BigDog]

Did a 100 mile round trip today. No chirping, seems fixed.
