Cap In Hand And Begging For Help

[Scorpiorefugee]

I've always had a sneaking suspicion......

 

Perhaps we should stop this nostalgia before I start to really feel my age.

 

Or maybe we should start a new section just to help some of these youngsters gain a sense of perspective.

ooo eck.... credit to you both for still fixing your cars!! i am well impressed.

 

My dad gave up being a mechanic when they introduced computers to cars as he said it was no fun anymore.

Mum of 4,

 

Didn't you notice the reference to a '38 Austin 7. Sorry, a lass of your tender years wouldn't even uderstand any of that. I never owned one of those but I did own and run a 37 Standard 8 - about 30 bhp - WOW!

 

I wonder if SeatKid knows about these old things. Good old side valve engines, no heaters, radios or turbos to worry about. Semaphor indicators which meant you operated the switch and then had to turn and bang the door pillar until the damned thing decided to pop out of its hole before you turned. Not a problem really because the speed that they used to do meant you had loads of time before you got to the corner.

 

SeatKid,

 

Thanks for all of that useful info. Unfortunately, my old thing doesn't seem to fit with any of those.

 

The problem seems to come and go at it's leisure although it is pretty persistent in it's faulty state. It seems to clear if I gently increase revs in second and can clear briefly when cold. The engine does sound harsh when faulty but can instantly return to its normal buzz. No smoke, whistling or anything other than a reluctance to respond to more than 25% of pedal movement.

 

I am however now a little wiser and maybe able to use this to advantage but, right now, I'm tired.

 

Must be my age. :wacko:

 

 

Clearly you know that your car seems to be acting like it is in "limp home mode"? usually when nothing too obvious stands out, it turns out to be one of those ghastly sensors or a faulty dirty connector to it.

Thanks Gio,

 

I should agree but when it's gone into limp mode bofore it has always needed to be switched off before it resets. This time, it just suddenly picks up, but only if I let it rev above 3500 in second for some reason. I am beginning to wonder if it just needs a good thrashing to blow the muck out 'cos it seems to have been better since I've been changing up at 3000 rpm instead of 1500.

Quick update.

 

I've now had a good look around and all hoses seem in good condition but something strange...

 

I seem to have 2 boost control valves connected in parallel. Each has it's own supply and they are definitely original. :wacko:

 

Also, for what it's worth, the usual 'diesel rattle' is noticably worse under fault conditions.

hello

I have had one of these cars that kept going in to limp home mode, (required ignition to be switched off and back on) turned out to be a couple of faults,

first, the turbo wast gate was siezed and would not move, when that was replaced the fault was still there but not as bad, second, we replaced the vacume hoses because they were clocked up with oil, this cured it,

[Scorpiorefugee]

FOster,

 

Thanks for your input. I'm getting roung to thinking that it has something to do with gunge in the pipes, partly because of its high mileage and partly because of the gunge I found on the air temperature sensor when I took it out. Also, when I changed the MAF 70,000 miles ago, that had a good coating of black sticky stuff.

 

Unfortunately, this model doesn't have a waste gate but there are a couple of solenoid/valves in the vacuum circuit which I want to get out but it will have to wait for a bit.

 

I have read somewhere about faulty injectors causing knocking so, since the fault symptoms include excessive diesel type noise, that is another avenue for investigation. In the mean time, I have ordered a VAG Com reader just to see if it helps.

 

Needless to say, If and when I get a result, I shall update this.
