Golf MK4 Engine problems!!!!

**michaelkayll** · 03-08-2006,10:37 AM

I have a 2000 (W reg) mk4 1.4s 16v with 50k on it, my problem is that the engine 'judders' when standing still & it feels as though it might cut-out but never does. It started doing this intermittently about 2000 miles ago but does it nearly all the time now! Does anybody know what may cause this?

The cambelt hasn't been changed yet but would this cause the (for want of a better word) juddering?

Thanks!

The cambelt in these engines is the same as any other fibre product, over time it will stretch slighty, fray and perish. Failure of a cambelt will create a huge inconvenince for you. I have experianced this juddering before, and despite looking at all the deep issues i missed the basics for a long time. The cam belt had stretched and the timing was every so slightly out, although the vehicle would drive as normal it would judder and the revs would bounce on occasion at tickover..My advice would be to check your timing belt, get it changed if its due and see if the problem persists following this.

Hi
Hive you solved your judder problem yet? I have A 1999 Golf TDI same problem. Would like to know if anyone has had this fixed.

You will probably have a throttle housing bunged up with oily deposits from engine breather system...
Solution, Take to dealer to have throttle housing stripped cleaned & base settings reset...
90% sure this will be your problem
Hope this helps Golfer7
Let me know outcome...
P.S. any garage competent garage could strip and clean throttle housing but revs may hang/stick after this is why base settings may/should be reset after...
P.P.S sometimes maybe 1/10 will go bertie

ECU is learning the fueling maps by himself but its easier to download(have the dealer do it ) the right program. Bassicly you just remove battery , switch lights on and off to clear static and reconect. Drive car normal and take it on the motorway and give it somme stick ! Put the engine trough all driving loads if possible ! It takes about 2 days for ecu to learn.

Hi yes the judder problem is due to the duelmass flywheel apparently! fitted tjis will cost me 700 pounds. I have had power loss aswell and have just hsd the air flow meter replaced. What a difference.
