Hi All.

I have a 2019 1.5Tsi DSG and a couple of times yesterday I noticed a bit of a squeel (lasted less that 1 second) when pulling away from a mini roundablut type scenario - not a full stop. - I did not drive over the paint on the roundabout, it was more the first 30 yards on the road after the roundabout. I have a good set of tyres which are not prone to wheelspin so don't believe it is that. The Climate control was on and the car was fully warmed up (it was 1/2 hour into a 4 hour drive home). It was a hot day but only about 10am at the time and about 18C and sunny. It kind of sounded like the old fanbelt slip noise you used to get in the olden days or the squeel you hear in a car park that has a shiny floor. Am I right in saying that the car doesn't have an accessory belt that is seperate from the main cambelt? I guess it could not be that slipping otherwise the engine would blow up right? Could it be a sqealing alternator, waterpump or something like that?

It only did it a couple of times and then not again for the whole of the 4 hour drive - which about 1 hour worth was on smaller roads and the rest on the motorway. It just made me worry slightly. The milage is quite low (40000 and it is a 2019 car). I was not planning on having a cambelt change now that it is "for life" so I hope to goodness it is not related to that.

It did it once before a few months ago but it is very very infrequent. I have an all-in-one plan in force and it is due a service in a month or two (and an MOT). What (if anything) should I report to them (in a way that does not get them sucking their teeth and suggesting a £1200 cambelt change) :-) There is no way I would be able to reproduce it as - like I said it only happened a couple of times on this drive and once before several months ago. I am 99.9% sure it would not happen on a test drive.

cheers,

Paul

I thought the accessory belt WAS separate from the cambelt.

Ah-ha - I didn't know that. In that case could it conceivably be that slipping every now and then???

Someone who knows these engines well (better than me I mean) and works on them regularly could maybe give their view :-)

Strangely, I have heard this noise, twice last week. Once left turning, leaving a shopping centre, onto a busy, but urban A road. The second was turning right, at a set of traffic lights (4th in queue, so rolling already). I just assumed it was the hot road surface, as very hot on both days, and tarmac “polished”, rather than melting. Yes, it was like the old slipping fanbelt sound. Couldn’t replicate today, although another very hot day.

I wonder if it could be just the road surface as you say. I hope so :-)

I have Michelin Crossclimate 2 215/50R18 tyres - what do you use? The tyres are 2 years old but plenty of meat left on them. I am very happy indeed with the performance of the tyres all said and I would definately get another set when they reach the end of their life as they totally eliminated wheelspin for me when taking off, uphill on a slightly damp surface.

Cheers,

Paul

Could be the aux drive belt when there’s an extra electrical load, power steering assistance is now from electric motors rather than hydraulic fluid. Tight left or right turn combined with an extra grippy surface and air con running could cause a squeal from the drive belt.

I'll get them to check that out when the service is done next month in that case.

What I have done is rotated the tyres (front to back) to even out the overall wear today - great fun with the supplied jack and space saver spare wheel. 8x jacking up - My goodness those 18" alloy wheels are heavier than you would think!

Had been meaning to do it for a while as they are all seasons I want them all to wear out together if possible (so I can choose to replace them with another set of all seasons or someting else). The upshot is that I am hoping that the slightly different wear pattern at the front will eliminate the issue. If it does then I will know it was the precise wear of the tyres /polished road surface at the time rather than anyting more sinister.

Did it again today, but it was a quick exit, from a side road with either way zero visibility, due to curve of main road. Definitely front offside tyre (windows and roof open), so parked up and walked back. Again, road surface looked polished, and very smooth tarmac (no potholes, filled or otherwise).

My tyres are factory fit Slovenian Goodyear Eagle 215R18 (I have the short lived 18inch fitted wheels, on 23 plate). No sign of early wear, but only 6000 odd miles, since new.

One thing about roof and windows open - driving into garage, I think I can hear a loose baffle, in the exhaust. If it is, I might give insurers a heart attack, and fit a sports exhaust 😂
