Hi all,
I hope you can help, my sis in laws car a (99) v reg golf 1.9 TDI has just developed a fault tonight where it is cutting out when reved.
I have already had a look over it for any split hoses etc but can't see anything obvious i know it has had a new air flow meter fitted about a month ago.
Any help would be greatly appreciated as the local garage isn't open till monday and she's had to leave her car at mine.

Will it idle OK? After it has cut out; will it restart?
Why was the MAF changed and where did it come from?
|
Hi screwloose,
It restarts straight away and it seems to idle fine but as soon as it's reved it cuts out, iv'e just asked my sis in law why they changed it and she was told by the garage it was clogged up,
She bought the car a couple of months ago and it has been down on performance since she bought it, the garage told her that when they changed the maf that it would make a big difference but it hasn't.
She said it's been really bad on acceleration the last couple of days and tonight is the first time it has totally cut out.

Try it with the MAF unplugged. [This will set a code.]
Any chance of the engine code? There were seven versions of TDi in '99.
|
|
i will try with the maf unplugged and see what happens but i haven't got the diagnostic equitment to get the codes will need to wait for the garage for that, i never realised that vw took out that many versions in one year.
|
The engine code is on the label on the cam-belt cover; inside the front cover of the service book and on the build label under the boot floor carpet. [AHF; ANU; etc.]
|
|
just found the engine code it is ALH
|
That makes it a 90PS non-PD unit.
As well as the previously-mentioned fuel filter, [that's well worth replacing if it's not new-ish] these can suffer odd faults due to failing engine control relays. [Know universally as "Relay 109."]
MAFs only "clog up" if some gullible youngster fits a K+N type air filter. If the new one didn't come from the dealers, then it's probably useless anyway.
|
thanks screwloose i will definatley check the fuel filter but im sure that was replaced when the new maf was put on as the car was serviced, the relay sounds interesting my mate has the same car so i wonder if i could swap out the relay easily to see if that cures it.
the new maf was bought from VW so it should be ok.
|
If it's the same part number on the relay; then it should be OK to try it.
All types will have "109" printed on them - that's it's function, not it's part no.

Hi,
Just to update this post i eventually found the cutting out fault to be a loose pipe but the car was still down on power. After taking it down to the local garage they have diagnosed a knackerd turbo could anyone please advise if these qoutes sound right
They have qouted around £600 for the turbo kit and another £300ish for labour it's my sis in laws car so she hasn't a clue about prices so asked me but iv'e never needed a turbo replaced so i thought i would ask in here for advice.
Regards,
Maretz

Nothing sounds right here. I can't see a "loose pipe" [where?] causing the engine to stop and rather that just saying it's "knackered," I'd hope that the garage gave some convincing and justified reason for their diagnosis.
Specifically, what it wrong with the turbo and why. After spending around a grand - who pays if it's just the same, or the new one fails too?
Also; was this bought from a garage or trader? All this should be down to then if that was the case.
|
sorry should of explained better the garage came out and i left them to look at it the bloke just said it was a loose pipe it's all fine, but when driven the power was still lacking to what it should be, it was my sis in law that took it in thats when they told her the turbo was gone, they never gave any justfied reason and i know next to nothing about turbos so your advise is greatly appreciated.
The car was bought from a private sale so she has no come back.
|
It's not relevant now because you've found the fault, but I have found on a few occasions where the fuel filter had developed cracks on these, possibly due to the clamp being overtightened. This would allow small amounts of air into the fuel system, and cause intermittent cutting out. Also the cracks would not be visible with the filter in situ, and therefore not immediately obvious.
On one occasion on a Sunday afternoon in the middle of nowhere I didn't have a spare, so I soldered up the crack as a temporary repair.....
