VCDS is probably the best known and reliable one to use

It sounds like you may not have plugged something back in or even the plugs connected to the wrong sensor? If definitely sounds like it is not it is not reading a vital sensor reading or an actuator is also unplugged

You should be able to get a fitting kit to include the Air Mass Meter if fitted

Should be in the boot area under the carpet https://www.touchuppaintking.co.uk/paint-codes/vw_paint_codes.html#:~:text=VW paint codes - Location&text=The most reliable location is,section of the boot area.

I would be surprised if the injectors were affected by going through a deep puddle. More than likely is that the engine ingested water into the engine via the intake (can be seen by air filter being deformed by water ingestion) and this can lead to hydraulic lock in the cylinders which would result in lower compression on one or more cylinders. I would run a compression test on the engine cylinders to determine if there is any drop in pressure

Not sure if that's an internal or external fault. Maybe worth starting at the fusebox and working your way back to look for corrosion or loose connections

Hi Matt......welcome to the Forums You are obviously a big fan of the Touran then? Good to have you onboard

It sounds like a strut top mount that is failing and is easy enough to replace if you drop the shock absorber/spring down

Have you disturbed any vacuum lines when you serviced the vehicle?

I believe there are specialist audio companies that would install the software but if not then £250 is a bit steep but you would know the install is reliable and up to date

Hi James.....welcome to the Club Good to have you onboard

Can you get a photo of what is there for you to undo (head of bolt, etc)

Yes, usually if you unplug the MAF and it runs better it means it running on a default setting and the MAF is defective. Maybe it is a defective one and a new (quality) one will resolve the issue.

It could be a combination of carbon build up in the turbo and EGR (and DPF if fitted) amongst other things. Maybe the engine would benefit from a Terraclean or similar to remove all the carbon and freshen up the performance.....not too expensive and plenty of companies offering a mobile service

Thanks for letting us know

I would have thought the glovebox would be the same for both saloon and estate variants.

Sorry, not sure but worth speaking to your local dealer to see what part numbers are available

I would probably stick to the stock turbo if electronically controlled variable vanes and wastegate. If you change turbos then it should be possible to remap it I would imagine

Hi It does sound like it could be EGR. Maybe the best method is to fit a blanking plate in the EGR but ensure it has a small hole in the middle of it to get a small amount of gas flow to satisfy any sensors

I would think that would be more reasonable

Hi Charlie.....welcome to the Forum Sometimes you can have the best fun in a small car....just look at the Toyota GR Yaris or Abarth 500, pocket rockets to say the least Good to have you onboard

Looks like a cylinder head location dowel to ensure the head doesn't shimy sideways but probably get away with it if you have the other one in place and bolts torqued down nicely

Only if you lower the profile to ensure the wheels are under the arches or huge negative camber

Hi....welcome to the Forum It sounds very much like the heater matrix may be leaking slightly and causing antifreeze vapour to enter the cabin area. If there is a small pool of liquid on the floor in either footwell and the windscreen is misting up inside then the matrix is leaking

If you connect the two parts together then it should form the shape of the part it fits to and then just go looking for it in the engine bay. It may be wise to look from underneath if possible to see if on the underside of the engine
