Any way to check cross compatibility across Vw group? Can seem to find these from golf’s or Leon’s but struggling for an Octavia one

Thank you!

It’s a 04L 129 766 Q on it

Have tracked down a coolant leak to the charge cooler (camera through IAT sensor and wet inside). I’m trying to track down a compatible part, new genuine is around £800 so looking for second hand or eBay. Anyone know how to confirm compatible part numbers? Latest revision according to the dealer is 04L 129 766 Q There are lots of other revisions out there so not sure what fits. A few AJ revisions on eBay, but can’t track down whether they will fit. thanks

So my apparently trained Vw mechanic couldn’t find the leak. Ordered an endoscope, removed the intake air temp sensor and had a nosey. Whilst looking inside a few drops of water rolled past the camera, so looks like it’s my charge air cooler leaking! Easy to check with a wee endoscope if they can’t get to the bottom of it.

A few ways these engines seem to lose coolant. Mines currently at the mechanics for similar symptoms. in no particular order: water pump leaking egr cooler leaking charge air cooler leak blocked matrix causing overspill from expansion tank head issues

Do you feel it in the pedal or the steering wheel?

Should be grand. Did a battery swap with no issues like that

Slave would be my guess. Had the same at around 100,000 miles. It started quite some time before it finally started sticking to the floor, but only from a cold start so didn’t really pay any attention to it.

Keeps the engine bay cleaner. That’s the only thing I noticed

Slave cylinder is within the clutch

Big redd ship new pins with silicone grease. Silicone seems to be the preferred option if not going for the expensive trw stuff. have also seen a tip that you can trim a bit of the rubber bush off if they swell, ie shorten it to allow more room for it

If you don’t have trailer prep, I think the look needs to go back to behind the glovebox. your other query about cooling etc is also valid. There are some models that require upgraded oil coolers, just not sure which. Not sure if trailer prep actually includes this or just the loom. Hopefully someone else has a better idea. There’s definitely info somewhere online about it as read it before I got mine fitted.

What did you need a hex head for? On my Vrs tdi rear brakes there are none. Might be a bit of a red herring for the op. M14 spline needed for the rear carriers, 17mm and 13mm spanner for callipers and piston wind back tool

Slave cylinder is within the clutch. Had the same issue at about 7 years old and 80000 miles. Had the clutch and dmf replaced as it was all apart anyway. £1200 is excessive. Close to what the dealer quoted me. Clutch kit and dmf cost £720 and then £160 to fit.

Surely it’s no6 on that diagram you need?

Should only be a sensor on the front pads. I would recommend the trw from AUTODOC. Tried brembo from euros and they warped on me. Their pads also rattled in the carriers. be prepared for the rear carrier bolts. Very little room to get at them and a high torque

What brands recommended as a replacement? Think my gates pump is leaking since being replaced in 2019 at 50000miles or so. 2014 Vrs tdi 110000 miles

3m vhb or number plate pads maybe?

Was the slave cylinder changed when they did the clutch? slave cylinder went in mine. Exact same symptoms. Pedal sticking to floor. New slave cylinder (clutch and flywheel done at the same time as everything was out) sorted it

Wouldn’t recommend the brembo pads. They knock a bit Sometimes in the carrier. The trw pads are a perfect fit (the callipers are trw I think). Would avoid pagid. Just had to replace my rear pagid pads as the material had come away from the backing

I had the same issue with brembo discs. Replaced with trw and had no issues

There’s an issue with some tdi’s that they take longer to crank. Some have had updated software to rectify. Could be that. Also believe the fuel filter is recommended for change at 40k miles.

Happens if you mix different forms of screen wash. Should run the tank empty before switching

Towbar prep was an option from the factory. If not on your car then a cable will need to be run to the glovebox area to connect the wiring properly. Salop towing were the cheapest when I had mine installed a couple of years ago. They did a very good job with a westfalia towbar
