Hi All, first post here so hoping you can provide some advise I've had my Golf Mk5 (2007) 1.4 TSI 170 for nearly a year now and the engine warning light came on! The car wouldn't rev properly and that has since been rectified under warranty by replacing the chain, which appears to be a known issue. Although it pulls through all the gears properly, there is definitely a misfire on idle. I can't be a 100% sure whether the misfire was there before the timing chain issue but if it was, I certainly notice it more. I've had someone check the ignition coils and although they are the originals, they seem fine. The spark plugs are new, compression in each cylinder is fine and there are no warning lights or engine codes present. I'm going to take it back to the garage who changed the timing chain however wondered if anyone on here has had a similar issue and can provide some advise?!? Cheers in advance! Oh and the car has done 54,000 miles.

Any chance you can supply me with any information on this problem?
Im having the same issue with my vw golf 1.4tsi. It misfires on low revs and all checks done by VW garage to date indicate no fault is present. I had the timing chain issue and that was replaced completely. Ive also had the petrol pump changed and the spark plugs. None have solved the misfiring problem. Really stressful because car is out of warranty so having to pay mechanics and parts a fortune for no results!!
Any help would be awesome.
Get them scanned as these engines are terrible for chains and cylinder faults
Thanks for your interest in this thread.
The car initially had the annoying noise made by the timing chain fault which the garage repaired. I had noticed during that time that the car misfired too and the VW garage told me that by repairing the timing chain issue this may solve the misfiring as it is closely linked to the valves. The annoying startup noise did go away but the misfiring continues. The car has been connected 4 times by the VW garage to its computer and has also been accessed by VW Canarias (the official VW importer for Gibraltar) whilst connected. No faults are present according to the computer. The last suggestion by VW was to replace the petrol pump which came at a cool £400 and hasnt solved anything. As the car is out of warranty, i cannot simply continue to chage parts until the problem is found :$. I thought perhaps someone had experienced a similar issue and there was a common problem which i could relay to the VW garage.

Its possible its related to the chain issue as we have replaced engines due to this fault
You will need to get the compressions checked and the fault codes read
Sorry for my lack of a reply, since I started the thread!
So here is the current situation. The timing chain was replaced about 55k and I've done nearly 10k since. I've always felt on idle that the engine is lumpy such as a misfire. I had the car in to VW to repair a door lock under warranty and the mechanic said he its definitely not running right and thinks the timing is half a tooth out. To do further check though he needs to start stripping it down and couldn't give a cost. This isn't covered under my 3rd party warranty so reluctant to pay.
I've just had a service at a local garage I trust, one of the ignition coils was replaced but other than that no major issues. He's ran various diagnostic tests and there are no fault codes. The only think he can see on the diagnostics is the occasional misfire which doesn't appear to be bad enough to raise a fault code? He's happy to check the timing but doesn't have the right gear for this specific therefore would need to buy the right timing tools.
Could the timing really be 1/2 a tooth out to cause this, but not out enough that the pistons are hitting the valves?!? If the timing was out, could it really be driving as well as it does, pulling fine through the gears and reving high? Or could it be something like the camshaft position sensor is faulty, even though it was replaced prior to the timing chain being done?
Oh and it's been compression tested, all seemed fine

The chains stretch and the tensioners fail. Along with other issues these need checking ASAP as they can and do destroy engines
If it is fitment error or the person that replaced the chain used the old spec parts and did not check the rest of the engine then its all down to him and you for not taking it somewhere who knows what they are looking for
It is NOT a case of just changing the chain on these engines
