Had egr replaced but still getting white smoke from exaust 5 days later

Morning John

Welcome to the Forum

White smoke can be caused by Condensation or a Coolant leak, Grey smoke is normally over fuelling Black smoke Way to much fuel. Does the smoke smell ?

So who Diagnosed EGR issues ? Who replaced the EGR (BMW or an Independent) when the EGR was replaced was the EGR Cooler replaced? Have you checked coolant levels to see if your losing any?

Loads of questions I am afraid before we can try and help 😁

Hi, sorry for just getting back too you, car dealership said they sent car to a bmw specialist who found fault and then dealerships mechanic replaced EGR cooler. I had to top up coolant when first received car back 6 days ago but it seems to have stayed at same level.

OK so if I understand the situation the car was purchased from a Car Dealer (Non BMW) you had a fault which you reported to the supplying dealer which they couldn't identify/fix. They sent the car to a BMW Specialist who diagnosed an EGR fault, the car was returned to the supplying dealer who then replaced the EGR or was it the EGR cooler they are separate parts ?

So first question are you still seeing white smoke/mist from the exhaust does it clear or is it constant ? Next question have you checked the coolant level again ? Last question I have assumed your car is an E84 model with the N47N engine (1.8 or 2.0d)

Hi, yes thats correct. On the invoice it states the part was a egr valve. The smoke clears after around 5 minutes driving, it seems to happen after ive drivin 20 mile to work then when i leave work 9 hours laters it smokes. The coolant level has not dropped which i checked this morning.

Sorry yes its the E84 model

Hi John

Considering the low temperatures over the last couple of days condensation vapour is normal, also as it clears after a few minutes driving and coolant levels are stable it would indicate no leaks.

You need some warm weather to see if with warmer temps it should almost disappear

Good Luck
