I can't see it being wise to spend a load more cash on a walnut shell blast on a hunch from a garage who appear to apply a 'just change everything we can think of' approach to diagnostics. Does the coolant temperature gauge sit at 90 after a few minutes running?
-
I don't know much at all about 1.4 tsi engines, but I'd be pretty surprised if carbon build-up in the intake was causing that. Do you have any fault scans?
-
Which measurement of the emissions test was it borderline on? There may well be other factors unrelated to carbon build-up that could be responsible. I'm curious to know why this tester is sure that carbon accumulation is the problem.

I can probably help if you get no response. I messaged you a day or two back. Have VCDS.

Can generally be found molded into the plastic of the bulb holder, for example:

No VW group cars in UK are given a 5 year cambelt change recommendation any more, as far as I know. Approx July 2023 this (UK only) stipulation was withdrawn. Don't think it matters when built. Mileage only, varying with engine type, quite high mileages now, I believe. Do a bit of a searcharoo, there's an abundance of discussions about it.
-
Probably not. 5 year interval is no longer used.
-
I have no idea how they can judge that the drums need cleaning, without removing them to look inside. They will not have done this, unless you specifically asked them to, I would think. If they had looked, it's only 5 minutes more work to clean them out while they're in there! So I would recommend ignoring this dubious suggestion and letting the MOT decide if it's really required.
-
Has it had the MOT yet?
-
VW group in UK previously recommended every 5 years, but that was dropped in mid 2023. Not sure if there is any time interval at all now, but mileage recommendation varies with engine code, big distances though.
-
No, not according to current recommendations.
-
If cambelt and tensioner was only done 40k and 5 years ago I reckon there's very little chance that is involved in this rumble or likely to cause any other problems for a good while.

Not tested.

Please let us know the outcome. 🙂

I guess that looks encouraging, but if the check engine light was on, a code should have been stored. What made you think the tensioner failed? I could lend you the timing tool kit and potentially some help to use it if you're not too far from Highworth. Shall I start a PM chat with you?
-
I think a single-tooth skip might not be catastrophic on that, but I'm not sure. Whereabouts are you based? There's an inexpensive timing tool kit that could be used to check the current situation, but it needs a little effort and raising the car a bit off the deck to fit the crank tool.
-
Chain engines can usually be distinguished fairly readily by the chain cover being sealed (because it has to keep oil inside). Belt engines have looser fitting, unsealed timing covers.
-
Engine code is often on a sticker on the upper cambelt cover (for belt engines anyway). Also on V5. See: Engine code and why it's useful to know - Handy Topics & Guides - BRISKODA
