    Audi B8 2.0 tdi CAGA coolant temp problems

    Just my input again on this. I have changed both the EGR thermostat and main thermostat with genuin parts from TPS and still struggle to get to 90 and maintain with the heaters on. I pulled this matrix pipe with the bleedhole today with the engine off and immediately it shot coolant out which...

    EGR has died again CJCB

    Hi. Last summer my EGR cooler cracked resulting in coolant slowly being burned off. I replaced this with a brand new unit. Today while driving I hit limp mode and after checking with VCDS I have code P0403 EGR malfunction. I have checked all connections and nothing seems out of the ordinary...

    Another thermostat thread

    Hi, The timing belt and WP was replaced by Audi November 2020. 13k miles ago. My EGR cooler then cracked in the summer, I replaced this and that cured my coolant leak/burn. As I lost a majority of the coolant, I flushed the rest out and used Granville Rapid Cool 50/50. I asked the garage...

    Another thermostat thread

    Car is a 2014 A4. Engine is a CJCB. B8 FL. I've replaced the thermostat and inline/EGR thermostat with Genuine parts from Audi and the car is still not reaching 90c with the heaters on. I know these engines are very efficient but there's people out there with the same engine that do hit 90. The...

    Audi B8 2.0 tdi CAGA coolant temp problems

    Hi John, If you have this hose/valve, look at the top of your engine, above where the inline thermostat is and you should be able to see the one way valve hose. It's a small hose, about 6-8inch long and has a bulge at one end. It is also marked up with green writing and the product code 03L...

    CJCB Temperature problems

    Hi Hudson. Did you change the secondary inline thermostat? Also, does yours reach temp with the heaters off? Finally, when was the last time it visited Audi?

    Hi, Firstly the car is a 2014 2.0 TDIe 136bhp CJCB with 117k miles. The car will not go past 75/76 with the heaters on. Unless I drive at 80mph. I have replaced the inline thermostat and the main thermostat with genuine parts from VW. I have also tested the sensor using VCDS by comparing the...

Constant driving, no stopping, coasting and pulling away. Temp gets to about 75c on the gauge and oil gets to around 80c on the lap timer. Heaters...

    Carplay.

    Hi, I have a 2014 A4 with a concert and Carplay/AA installed. When I press the talk button on the steering wheel, I get both Siri and the Audi voice command listening at the same time. If I use the left scroll on the steering wheel to navigate the carplay, it changes my DIS from whatever I...

    Lots and lots of white smoke!

    Hi, thanks for the reply. I did do that and didn't lose any coolant at all but still got lots of white smoke. I assume this is the coolant burning off that's sat in the exhaust? I have now replaced the cooler but lost a bolt that attaches it to the engine so currently sourcing another one. A...

    Lots and lots of white smoke!

    Hi, I've been told that it may also be the EGR Cooler that's cracked. I've just started the car this morning and it started fine and idled fine again. After 30 seconds or so the coolant started to go down quite noticeable and the white smoke came. Is thus a common problem and is there any way...

    Lots and lots of white smoke!

    Hi all, on a leisurely drive today taking in the sunshine I pulled over to have a quick drink and talk with a friend. After leaving the car for 10 mins, when I returned I was greeted with a lot of white smoke and a warning saying to stop engine and check coolant. I did and the bottle was empty...

    MPG 2.0tdie

    Cheers for the input. I have put £20 of Shell diesel in the tank and been driving normally this week, only work and back. I reset the counter straight after filling and this displayed 200 miles remaining. I have only done 14.8 miles and the car is displaying only 130 miles remaining. Surely...

    MPG 2.0tdie

    Thanks guys. The gold didnt didn't warm up any quicker but I was getting 45 around town normally. But I have to bear in mind this is a much bigger car and a little bigger than a 1.9 lump. Also I chose a diesel as I'm a football fan and do travel twice a month to away games. Not only that...

    MPG 2.0tdie

    Hi, I purchased my 2014 b8.5 2.0tdie 90k miles last week and think I may have already discovered an issue regarding the MPG that I'm getting. I like 3 miles from work, so 6 miles of traveling per day just for work. In between that I do the usual mid town driving on 50/60 roads and I don't...
