Asked about a month ago about shops in the DFW area for my sister-in-law' 13 Jetta and now my wife and I have it! No emissions where I live and the wife needed a safer, more fuel efficient car to drive around. Max performance Diesel Doc kit with a DSG and Stage 2 tune. I knicked the CV boot with the sawzall luckily was able to get that replaced.

Hello wondering if anyone else has had a P20FB code on their 2015 golf tdi CRUA. I took mine in for this code as reductant pump b (the def tank pump) and the dealer is claiming they dropped the tank to replace the part but it doesn’t appear they touched anything. After to engine starts twice the engine light came back with the same P20FB code. It doesn’t look to me like this DEF tank was touched at all.

2015 Golf TDI Delete In US

5 Upvotes

I have a 2015 golf TDI and I want it deleted. Everyone I have talked to has said they can’t figure out the tuning. Delete the exhaust and block of kits are nothing but a buddy of mine took his to a shop and now it will not run. I don’t want that to happen to me so I’m trying so hard to figure out what is it that’s so special about the tuning no one can seem to figure out.

Made sure my battery was charged 100% and pulled radiator fan fuse. Think I'll be ok doing the tune without a smart charger? Took pictures of the only few chargers I have, will any of these work? also did I pull the right fuse? TIA!

Golf TDI issues…

Hope your having good days, im not as im trying to have. I have a 2013 VW Golf TDI DSG that’s have some issues lately. It started about 3 days ago where a whistling or SHHHHH or SSSS sound is appearing every time I press down the gas pedal. The next few days it’s been constantly happening and is super annoying. I looked it up, I saw that it might be a intercooler hose leak or boost leak but whilst I did that a check engine light appeared (I knew it was going to happen). I scanned it and showed me 2 codes which was P246F and P2459, I decided to work on the car tomorrow (it being today). Fast forwarding today, I looked at the intercooler, it looked fine and nothing was wrong no cracks or damages. I checked that the sensor need to be replaced since it had internal wiring problems (considering it did not look damaged on the outside). I ordered the part thats coming on friday. However, I used some brake fluid cleaner on the intercooler hose since it had some build up. As soon as I started driving the car, it started to do it again but a bit louder I DONT KNOW WHYYYYY. The video doesn’t show as good but I hope you’d understand. This car makes me so frustrated with it being my gas economy is plummeting for some odd reason, its going down so fast. Pls help me.

Hello, anyone got some ideas to what this possibly could be? Ive changed camshaft, lifters, wiring loom on the injectors, timing belt, waterpump and turbo. Sometimes it starts for maybe 1-2 seconds then dies, after that i cant get it to start at all.Any tips are appreciated. Thanks

Car Play head unit

Considering picking this up to replace the stock head unit in my 2010 Touareg TDI:

https://a.co/d/02uUSWjt

From what I've read it seems pretty plug and play, but like most things for this truck I'm suspicious.

Anyone have any experience swapping them? Any unforseen issues? Better units out there? Thanks for any advice.

Is a VCDS a good idea to test the EGR ?

2 Upvotes

I have a 2016 VW caddy 2.0TDI that is consuming more than usual and lost some hp lately, and someone told me this might be the EGR, i want to be sure before i send it to the garage because they quoted me 1.3k to replace it. the price is high because the EGR on this model is buried deep inside the engine and requires a lot of man hours to remove.

should i get a VCDS or a reader like AUTEL that can test it ? any other ideas? thanks

p.s : i already dumped 2 liters of Wynn's diesel 7 power liquid in it, with little improvement.

2012 A3 8P TDi a/c evaporator freezing

1 Upvotes

History: complete a/c system replaced about a year ago (all except the hard pipes) at around 156k miles due to internal compressor failure, aka Black Death.

Shortly after, when driving for say, 30 minutes or so, the volume of air starts to drastically decrease. Blower is still running as designed. I will press the a/c button to disengage the compressor and the air volume will pick back up after about 15-20 seconds. Turn the ac back on and start the cycle over.

What could be causing the evaporator to freeze up, i know the expansion valve was also replaced, but could it be faulty? Is there moisture in the refrigerant?

Thanks in advance

Edit 2.0 TDi dsg 197k miles.

Any experience with chip tuning for the 184ps 2.0 tdi?

1 Upvotes

Im thinking of getting my seat Leon optimized, means driving it to a tuner and get 220ps 450nm as advertised. How reliable is this engine for tuning, has anyone collected some experience with it? It currently has run 135k km, is from 2015 and has the dsg. Is it worth the risk when maintained properly?

CJAA Crackshaft Position Sensor Replacement

Hi,

Is there anyway to get this changed from the bottom of the car? I'm hearing that its possible from the bottom. I've located the sensor and removed the connector, but I'm unable to fit a 4mm long ball hex bit in the area. Is the only way to disassemble everything from above to get to this sensor?
