Lane change sensor failure

Volkswagen Passat 2016 Wagon 15000 miles
The rear lane change sensor is not working. Dealer tells me some very minor grazes on the bumper are to blame and the entire bumper assembly needs to be replaced. Surely a scratch on the bumper can’t affect the sensor?

I discovered that the wiring leading to the air flow meter has been cut and re-wired however, the re-wiring was wrong. The wiring was readjusted and the air flow meter began working again.

No Crank No Start

Volkswagen Passat 2015 TDI SE 2.0 72000 miles
I drove over a cone back in October 2024 and it cut the nox sensor wire harness and ground wire harness which runs next to it. The car still drove fine after without issue. It wasn't until I spliced the wires back together that the car will not crank or start. I replaced the battery and still nothing. I tested all the fuses and relays, all good. I have no clue what the problem is. The codes it has are: P048E Permanent Exhaust Pressure Control Valve 'A' Position Sensor/Switch Circuit High P229E Permanent NOx Sensor Circuit Bank 1 Sensor 2 C0300 Permanent Check report for des… Read complete

Sorry to say but it sounds like you potentially spliced the wires incorrectly or shorted them

Starting issue

Volkswagen Passat 2015 Tdi 125000 miles
About one year ago my Passat would crank over but not start. Since then I’ve had the fuel filter, battery, crank sensor and additional warranty issues fixed. I’ve had it into specialized Volkswagen mechanics and the dealer ship in about 8 times total. No one can figure out why the car intermittently does not start because there is no fault reading. It has happened during warm and cold days, right after driving and when starting up the first of the day. And ideas would be greatly appreciated, thanks.

Car struggles to start but runs fine

Volkswagen Passat 2001 Variant, manual, 1.9 tdi 170000 miles
My 2001 passat 1.9 tdi, struggles so much to start after sitting for more than 10 hour. It cranks but motor struggles so much to start. After starting, it runs fine. Pc diagnosis shows nothing. Even in dash, after runing car for too long temperature doesn't go past 60⁰C. I have changed temperature sensor twice but still nothing different. What could be the problem?

Spia Pressione bassa pneumatici

Volkswagen Passat 2007 Automatica DSG 250000 miles
Non si resetta la spia malgrado abbia controllato Pressione. La vettura ha sensori sull'abs non sulle gomme. Probabilmente è rimasto premuto il bottone sulla plancia
Potete aiutarmi?

No power 1.8T

Volkswagen Passat 2002 1.8T 165906 miles
The car has no power, sometimes it runs great and sometimes it doesn't and sometimes it starts to run really well up to over 4000rpm and it seems to jerk... what's new: vacuum hoses, maf sensor, turbo, fuel pressure regulator, n75, lambda before the catalytic converter, fuel filter, spark plugs... I've been dealing with this for a year and I can't figure anything out

Coolant system malfunction

Volkswagen Passat 2002 GLS, station wagon, manual 5 speed 170000 miles
Had the check engine light come on a few times, the code is something to do with the coolant system. The temperature gauge doesn't like to register. Replaced the temp sensor, flushed the system, and checked for air pockets... nothing. The fuse was a little loose for the gauges, replaced it. Any ideas? Unsure if directly related, but the radiator housing unit is dual fan. I've been told that only one fan (as it is) would be spinning until i turn on the AC. Should both be spinning regardless, or is that not normal and potentially connected to the issue at hand?

Idling - vaccum problem

Volkswagen Passat 1996 Sedan 260000 miles
The car is running very rough, idling at working rpm, does not matter hot ir cold. Stalls sometimes at traffic light. Oil found in the air intake. Pcv valve was replaced but did not solve the problem. Vaccum hose was found cracked, replaced, and it did run good for a while, but not for long. Then the plastic was found cracked at air intake, also replaced but still the same problem. Diagnostics are showing only the consequences of this problem but not the solution. It is burning lots of oil, needs to be reffiled every 150-200 KM so thats almost everyday. My next step would be removing lots of other hidden hoses (that requires lots of tearing down) for inspection, checking the sensors, wires, ground, fuses. Unless somebody had this problem and know what would be the solution.

Fuel system

Volkswagen Passat 2010 1.8 TSI CDA  124500 miles
Let's start from the beginning. Initially, I had problems starting the engine: shaking, misfiring, and unstable operation. The manual showed the fuel pressure in the system. First, I replaced the fuel injection pump, which helped for 3,000-4,000 mph. After that, it completely stopped starting. A quick study revealed that the in-tank pump wasn't working. I replaced the fuel injection pump. Then the same thing happened with the fuel injection pump. I replaced the fuel injection pump control unit. It worked for 1,000-2,000 mph. Now, when driving, there are misfires and low fuel pressure in the system. The fuel pressure sensor is damaged. Injectors can't fail like that. What should I do?
