Volkswagen Owners Club

I have twisted the lead going to the connection so that when it is on the coil the terminals are biased to the side slightly which I find makes a better connection

Hi MIke I do wonder if the fault started after the screen was fitted then quite possibly it needs calibrating to work correctly

VW may have a harness listed for aftermarket adaptions, but sometimes the wires are not used and some you need to swap around (red and blue I believe to retain the memory)

I suppose if we go on the assumption that it is the EGR then it is probably not getting driven hard enough to keep the valve clear of carbon. The only viable and cheapest option around this is to fit a blanking plug as all new EGRs will probably block up the same way

It could be a bad earth connection or lead, faulty alternator, loose belt, terminal corrosion on the battery terminals, poor quality battery (maybe pay extra for Premium one with more power), more use on the road during the daytime (without lights, etc).....in fact many other issues which would need further diagnosis

Try looking under the carpet on the passenger footwell side, there is usually a control unit in there which fills with water and causes issues like this

I would go to another garage and seek their advice as to the problem and any potential issues

The springs and wheel bearing are par for the course as these can go hand in hand sometimes. The engine revs sounds more like DPF or EGR blocked and this needs the codes reading to see which it is before proceeding with rectifying it

That is not unreasonable by todays standards for replacing the clutch assembly and flywheel especially at a dealership. Would have been cheaper at an independent garage. If the flywheel has had a lot of high temperature going through it from riding the clutch then it can show as blue in colour which means it is damaged by the heat. It would need replacing then along with anything else that may be damaged.

On the older Passat the ambient air temperature sensor would be mounted behind the front bumper area to measure the air when driving Not sure on later models.....but I would still look for any wiring going to your front bumper area Usually, simply disconnect, remove sensor and reconnect on a new one

Usually with RDS on AM and FM radio stations would tune in automatically as you drove through a local area and the signal was stronger. With DAB radio it is possible to connect to many more stations and geographically it is not an issue. However with DAB you do sometimes need an external aerial to pickup the DAB stations. On a 2020 car I would imagine this should already be built into the car?

Hi, It could be wheel bearing, brake pads slightly contacting wear lip or corrosion on brake discs, transmission......in fact quite a few things really. It would be advisable to get this checked by a local garage as a matter of urgency as it may be something safety related or expensive if something lets go Let us know how you get on with it all

Hi Mark....welcome to the Club To be fair, £320 is not a bad price for the spare wheel kit I have heard Honda charge at least double that for one for the Jazz

Would suggest the battery may be flat and need replacing? Test the battery voltage and if below 12 -12.5 volts then replace If the battery is sound then check the key fob locks and unlocks the car then try again as maybe immobiliser wasn't recognising the key

How did you get on with finding the fault with this issue?

....for a diesel engine?

A DMF is fine if vehicle is driven correctly but unfortunately, it is not always driven as it should be before you buy a second hand car and then inherit a worn flywheel. Fitting a new DMF is probably just as good as a 4 piece clutch kit with solid flywheel

The golden rule is 'if in doubt - change the belts' and don't forget the tensioners as well. There is no guarantee that this has occurred so I would err on the side of caution and replace everything in there (including water pump)

I would start with changing the filter and also an 'Air Con Bomb' which will purify the interior and kill odours

Should be checked with the ignition on and then slowly move the pedal down and up and the voltage should change Enjoy your holiday Tony 🙂

Good result and useful scanner to have for all the other jobs you may need to do on the car

Try airbag suspension which will raise it to a slightly higher level but also give superb handling on the very poor road surfaces you will encounter. Also gives assistance with supporting the extra loads you will be carrying.

Have you checked the camshaft timing as this could be slightly out and causing the sensors to be out of synch and this will throw the fault codes

It is quite common with modern engines to get to temperature as soon as possible nowadays as the time it takes to warm up on open-loop on the oxygen sensors is the time it pollutes most

A smoke test is the preferred method to accurately diagnose where the water is getting in If you have a sunroof then this may be the cause if the drain bungs and tubes are blocked
