strange coolant loss issue and smoke

**DJ_Steve** · 26-10-2019,11:45 PM

hello all,

recently got myself a 2005 b7 a4 1.9 tdi (115) which seems to be in excellent condition and i have an invoice for an engine replacement in the last couple months (car has 154k on but engine apprently has about 55k.)

but in the last 2 days i have started having major issues with coolant loss and white smoke, smoke seems to be worse when engine is cold but also can be when car is ticking over at running temp. but not every time car is running. car has still got full power and NEVER overheats.

now this would normally suggest a head gasket issue to me but from what i know that usually means overheating and a constant smoke rather than just when cold/idling

im wondering if it could be egr cooler maybe ? if the 115 tdi even has one.

should also mention car is sometimes slow to start and lumpy but i think thats due to glow plug relay fault.

i do have access to vcds if anyone has any suggestions to look at on their to point me in the right direction

thanks
