Hello, I have a Volkswagen Golf gti 2.0. I was driving when suddenly the transmission stopped working and the check engine light turned on. The error codes were 0784 and 0829. I turned off the car, erased the codes, turned it on again and was able to drive home normally. What is it happening?

2008 Volkswagen Golf 92674 miles
Once driving my car, I accelerate it and it does not respond properly and does not go over 1000rpm. When trying to speed it up, it does nothing and suddenly stalls. It also shivers and, when scanning it, the following failures were indicated: p441, p1542, p1171, p1426, p0108. Could you please help me?

The errors you mentioned have to do with the throttle body. Particularly, the code p0441 means that one of the oxygen sensors is damaged, but the rest are failures in the throttle body. Both the Volkswagen Skoda and Audi operate with computarized throttle bodies, which have a position sensor, which is the principal failure in your vehicle. Hope it helps you.

1996 Volkswagen Golf Mid 1996 Gti 2.0L 8v AFW 230000 miles
Bosch Polocup ecu, car idles correctly, able to do adaption and drives well but when i check dtc's I often get 65535 Internal Control Module Memory Error so i bought another one and took it to the same guy who did original one and he loaded the same map. I installed the ecu i bought and when i started it, perfect, cold start revs slightly higher and drove it untill warm,idle slightly higher but ok. Next day drove car,all fine. Start car that night and car won't idle,dtc throttle position sensor. Put my other ecu back in and all is fine still. Any ideas why this happened?

Check Throttle Body retrain. ECU needs to synch with new / different throttle body. Can do this with VAG software.

High Fuel Pressure on idle 140 bar + random misfires + fuel dilution

2016 Volkswagen Golf MK7 1.4 tsi 120000 miles
Looking for guidance on a persistent issue with my 1.4 TSI that is causing fuel dilution in my engine oil and misfires.
Persistent High Pressure: ECU is commanding and holding ~140 bar at idle (Actual = Specified).
Fuel Dilution: Confirmed smell of petrol in engine oil.
​Misfires: misfires at idle , but runs smooth at high RPM (more than 1200)/load.

Car will turn off while driving

2016 Volkswagen Golf Glow plug 90000 miles
Here’s an improved version of your text with better clarity, structure, and grammar while keeping the details intact: Volkswagen Golf 7 (2016) 2.0 TDI Issue – Need Help Hi everyone, I have a 2016 Golf 7, 2.0 TDI, which I bought from South Korea via Autowini. The car arrived in Albania on June 25, 2024. Initially, it had no issues, except for one time in traffic when the start-stop system was on—it turned off and had to be restarted manually. I didn’t think much of it at the time. Shortly after, I changed the oil, filters, and timing belt. I hadn’t driven many miles at that point. First Iss… Read complete

Whistling/blowing noise on acceleration and deceleration + metallic ra

2006 Volkswagen Golf 1.9L Tdi 105 137000 miles
Hi,
I drive a 2006 Volkswagen Golf 1.9 TDI with around 220,000 km.

Recently, I noticed two issues:

1. A blowing or whistling sound when accelerating and decelerating, which seems to come from underneath the car, possibly around the exhaust line or turbo.
2. A metallic rattling or ticking noise, especially noticeable at low RPMs.
Both noises are more noticeable when the engine is cold, but sometimes persist when hot. I haven’t experienced any significant power loss, and nothing shows up on the diagnostic scan (OBD/valise).
Could this be due to a leak in the exhaust system, a loose or damaged hose, turbo issues, or maybe injectors or valve lifters?

Thanks in advance for your help or similar experiences!
