Smoke coming from right wheel arch under engine - Cold Start

Rough starts would likely be the glow plugs, but the smoke from wheel arch is likely the Webasto heater

Hi. Thanks for the reply

I had 5 new glow plugs installed in December. 1 snapped on removal but is tight and secure. I would expect 1 glow plug to show a fault but why a second especially as they are so new?

What if the battery ECU is playing up from that fault code. Would this affect the power getting sent to glow plugs?

Can you control the webasto heater from within the car? How do you change the settings?

The battery one could just be a spurious error.. they crop up all the time..

Just noticed a transmission mount error as well, that would cause roughness too. You may just have a connection loose, so worth checking them, or you may be unlucky enough to have two faulty glow plugs.

I have just read my vehicle build spec and it states 'Without Auxiliary heater'. What else could be causing this smoke and bad smell?

Just to double check, plug in VCDS and click on 'aux heater' and see if it works

Beyond that, not sure, but worth dropping the underfloor pan and checking.
