Limp Mode 17965 Code

[boffa]

So the old Gal has started with the intermittent limp mode caused by the 17965 Turbo Boost Pressure Control fault code. I seem to be getting resistance from garages when I ask for a price to remove and de-coke the turbo, to the point where I suspect they don't want to take the job on. Has anyone had a garage carry out this work, and how much did it cost, and more importantly, did it cure the problem? There seems to be plenty of posts on here, telling me what the problem is (My car is a 51 plate 1.9 TDI 115) but I don't feel confident enough to take the job on myself. I would idealy like for someone to reccomend a workshop in South Essex that know how to take my turbo out and give it a good scrub up, without removing too much wonga from my wallet.

Try a vigorous "italian tune up" first to exercise/free up the vane actuator mechanism??

[boffa]

I found a local mobile mechanic to remove the EGR valve, inlet manifold and Turbo, clean and refit, all for £230. The EGR was in a terrible state, as was the inlet manifold, but the Turbo was causing the problem. The vanes could barely be operated using a screwdriver for leverage, but once the turbo had been cleaned, they could be moved freely with just your fingers. The work has solved the limp mode problem and it was money well spent if you ask me. Seatkid's Italian tune ups may be a short term fix but there is no substitute for a bit of good old fashion elbow (Acid) grease.

Yours was well gunged up by the sound of it which may be an indication of too much gentle driving? An italian tuneup can help keep things clean if done reasonable regularly and before things get too bad.

 

You got all that done for £230?? Good price.

[boffa]

Yes I thought it was a very good price, he was at it for about 6 hours and that price included gaskets, very nice bloke as well, and he used to work for the local Ford main dealer before going it alone! Your right about the gentle driving, The Mrs uses the car for four school runs a day, and the weekly trip to Asda, so it barely gets a chance to get warm. If anyone in South Essex (Thurrock) needs this work doing, message me and I'll pass on his details.

superb and great price. I tried the innotec which so far has worked for me (mine was siezed solid, couldn't move it at all with a spanner on it) but if / when it sticks again I'll get someone to strip it down. Hadn't thought mobile mech, will consider that for the future though!

Done all that new maf fuel filter it was a rubber hose conected to the turbo take the tray off and theres a little rubber hose that needs to be conected to a hose near the brake fluid container took me 4 hours to find and solve the problem worth a look

Hi guys !

 

Having similar probs with my GAL, 2005 mk2 115 zetec AUTOBOX,,

 

,Is an " italian tune up recommended with an autobox????   (am not a mechanic and  didn't want to try it and separate the box from me car like,,lol! and the correct way to italian tuneup plz?

 

Reply much appreciated!

You can do it with an auto but you will need to use gear hold positions, to prevent upward gear changes.

 

Don't do it if cam belt is near the end of life.

 

Don't do it with a cold engine

 

Make sure oil level is OK.

 

So ideally you need some open road with a long uphill gradient and some extra weight in the car.

 

Drive the car up through to third or forth depending on conditions hold at 3500 to 4000 RPM for as long as possible then allow revs to drop then repeat using the pedal to the metal.

 

What your trying to achieve is get the turbo vanes really hot and burn off the oily soot which causes the vanes to stick

I tried the italian tune up,,ahem ahem, here goes,,,got it in 3rd on an incline, foot down  only managed 2250 rpms and speed 60mph before i hit the proverbial wall and end of tune up,,,speed dropped to 50 mph  and revs reduced...the only tunes in the car were my effing and jeffing very vigourously, blue soot vapuors from me gob like,,lol 

 

got back on flat road got speed up to 60 n 70 mph in 5th  (both in autodrive and manual shifting up).....the problem seems evdent when carrying passengers and going up any slight incline..

 

me n my mechanic furiously scratching heads, he thinks the turbo's gone doolally,,,any thoughts?

 

Many thanx in advance toall the fantastic guys on this forum helping newbies like me!!! 

[gregers]

maf maybe??

do a search on this,as you say you hit a wall at 2250 rpms .

[seatkid]

This is almost certainly a case of sticky vane actuator. The reason you "hit the wall" and revs dropped off was that MK2 diesels will go into limp mode when the turbo boost goes out of expected range, and you can only  reset it by switching the engine on and off.

 

So despite my earlier posts :blush: , I don't think an italian tune up is going to work here. Its a case of working that vane actuator free, which can be done in situ if stiction isnt too bad - but to do it properly its a strip down job on the turbo/egr/manifold as outlined above in boffa's post.

[cheekyyumyum]

Many thanx gregers and guru seatkid!! :32: 

 

now to look for a garage that can strip down turbo/ egr / manifold who know what they are doing as well as not ripping me of f, had the pleasure of being HalFrauded re: Abs sensor  ...am based in Leicester, East mids, some of the garages i've asked have stated just change the turbo and be done with it!,,,

 

Any suggestions which garages or garage chains might do it, don't want to fork out money for a wishy washy job and be told its all sorted whilst a cowboy job gets done with the crud still inside the inlet manifold/ egr /turdo but i can'tsee it as all closed up (not visible ),,,,am not mechanically proficient, more like a an armchair theoretical average joe,,,lol

 

Thanx lads!!!

[cheekyyumyum]

plz correct me if i'm wrong ..

 

Turbo can be cleaned with Innotec cleaner,Intake  manifold with scraping offsludge n crud manually then in a bath of ferric chloride or petrol to strip remainder cr*p out of it.

 

With what doyou clean the EGR valve?

 

Thanx

[cheekyyumyum]

Hi Boffa!

 

have pm'ed you, appreciate reply. Thanx

[xavier]

Jack up car and support on axle stands.

 

remove under tray cover.

 

place soft comfy surface (e.g. old carpet) on cold, hard ground

 

wiggle under car until you can see where exhaust enters turbo. Look other side of turbo for actuator arm. Try to move actuator arm with finger. Then try to move actuator arm with spanner. If it's siezed solid, try innotec with the turbo in situ. I wouldn't worry (for now) about the intake manifold or EGR valve.

[Adam1]

One thing I would say about the innotec cleaner is the cardboard blanking plate is cr*p. I'm sure some else has mentioned this before somewhere as well.

Did mine the weekend and the cardboard gets wet then it all just runs out so impossible to fill the turbo with the cleaner spray. I would suggest using it as a template and making one out of Perspex or something.

Cheers mate!

> Perspex

 

I made mine out of perspex. Was fine when the cleaner went in (and you could see through it so you could tell when it was "full"). However it melted when using the acetone spray to rinse away the cleaner! Wood might be better, but then you lose the transparancy.
