GTI cutting out, oil light flashes

[Arri]

I have a1997 P reg Golf 1.6 GL

The problem first started when the battery went flat. I took it out and charged it. The car wouldn?t start at first and then it did. Then the cutting-out started. It seems random. Sometimes when driving, sometimes just idling.

I took it to my usual garage for a full service (?125) and they said they couldn?t find a problem. I booked it into a VW garage. When I went to take it in, the battery was flat so I bought a new one (?45). They ran a test with their computer and said it showed no errors in the log. One of the mechanics took it home with the computer attached. The next day they left it running all day and it didn?t cut out at all. They said they had checked all the electrics and something that can get blocked by carbon deposits. So I picked it up (65+VAT).

Sure enough it cut out again. So I came here. I just went to buy a new ECU relay. It cut out on the way. Part number 16590638 (?8.50+VAT). I put the new relay in (3rd from left on the top row of relays in the fuse box under the steering wheel). It hasn?t cut-out yet.

I?ll be back if it does.

I have been out and bought some of the above carb cleaner from a local auto parts place, but im now in two minds about how much to apply into the throttle body.

1. Loads seen as I am convinced mine is clogged up as it has never had any attention and gets driven around london daily

OR

2. Not so much as the spray turns to liquid and I am not sure whether this will harm the engine wherever it will run in to.

Any advice appreciated as I am thinking this is the main cause of my problems

Thanks

the yk 10 boost will not harm your engine you need to follow the instructions on the can it is very simple and you must use all the contents of the can you will find you will notice a difference in the running of your car

ok


the cure?

Ive been having pretty much the same probs but only when the engine is cold or has just warmed up 2 temperature.  After a few revs, it starts working!
My ECU is showing 2 faults which relate to the standard VW immobiliser so im off to get that fixed by VW on the 4th March!

well I finally found my problem... my cutting out was due to a faulty engine speed sensor (crank).  I had it installed today.... fixed the problem.

It's basically a f**king magnet and 2 wires that cost 120 quid... My mountain bike speed sensor works in exactly the same way, but was 12 quid!

Gday guys and gals,

Ive also had this problem on my mk3 gti 8v(95 m reg). Problem only happens when slowing down revs drop and it suts out.

Took car to vw today and they found a faulty temp sensor. Replaced that and paid ?86 part was ?19 oh how i love vw labour charges.

Will keep you posted as to whether the problem continues.

SURPRISE SURPRISE problem still there. Another ?90 well spent on highly qualified VW technicians(?53.50per hour @ VW St Ives)

Hello again to the cut-out regulars - just an update on my cutting out saga....

I had the 'cutting out for a split second' type of problem.
Replaced relay No.30 - No change
Had fault codes read - None shown for cutting-out related things
Had new distributor fitted (to change Hall sender) - No change

Car now does 3 types of cutting out! Yey!
1.) Cuts out for split second after warming up, usually twice per trip
2.) Cut out and stayed out for 10 secs with oil light flashing on motorway yesterday (which it has never done before).
3.) Stalled in Tesco car park and refused to restart with several re-trys, RAC called and it started 1st time for him of course! Was after about 15mins left alone though.

I am really tearing my hair out with this car now, I have lost all confidence in it and feel that this is a common Mk3 Gti problem that VW are probably aware of - if not then they damn well should be made aware of it! Too many cars have this problem for it to be 'normal' and coincidental!!!

My next plan is to change the crank sensor and the HT leads. If they dont work then I will be buying a Honda! Sod VW if this is the 'reliability' they sell their cars on!

Any further suggestions welcome. (May also try the 10k carbon cleaner too).

Hi can anybody please answer the BIG QUESTION

What is the fix for the GOLF MK3 GTI cutting out issue?

Is it a simple change of relay 30 VW part 165906381 ?

Please can somebody answer as its becoming very anoying! Thanks

Sorted out the cutting out issue  - I changed the relay 30 but it was still cutting out so i cleaned out the throttle body with carb cleaner and its all running fine now. No cutting out!
