Hi yes unlike the old days when you had a valve at the inlet side of the matrix its all about continuity of water flow to optimise engine heat control, get it up to temp as quick as possible and within strict demarcation maintain that temp to reduce emissions, Diesel engines run better when red hot but the problem is they produce more Nox 1 so to reduce this they introduced bigger radiators and fan packs as a trade off for lower emissions against total performance. Steve.

Hi am pretty sure it has constant flow as its part of the bypass system the hot or cold bit is worked by the air control flaps inside the air intake thus commanding the cold air during summer and warm air during winter. Steve.

Could it be injector issue or injector seal issue? Or a lambda sensor issue.

Welcome Graham and thanks for joining, Was this car registered in late 2020 rather than earlier in the year? If so, could, just could, be the adverse affects of cars sitting around for months awaiting components/ Covid associated. Kind regards, Gareth.

Hello Mario, We are going to need more information - such as:- Has it always been like this during your ownership ( how long is that)? Do you know if these springs have been replaced? How low is low? Measure from wheel centres to the underside of the wheel arches for each wheel, with the car parked on level ground. Kind regards, Gareth.

This seems unusual but also not surprising when you look at similar failures with other ev batteries and motors.
