The part is not ret received so the following is theory.  The apparent reason for breakage is due to slight shifting during installation of the new thermostat from its intended very shallow counter bore onto the flat surface reserved for the mating housing.  This causes the thermostat outer radius to create a high spot (should be flat when nestled properly) onto which the housing is torqued, snapping the casting. I intend to lock the thermostat into its C-bore with a thin coating of liquid gasket before mating and torque of the housing.

fairly sound, apart from the lack of power steering.

Reading a fair bit, it seems a super common fault, but have found various ways/means

and prices for resolving.

First up - is there any advice for checking what/where the fault actually is?

And how to identify exactly which motor/module is fitted?

Citi Auto Centre has a replacement (below) for £145.95 which seems fairly reasonable.

But also states there are 3 variants, plus of course whether this is actually the faulty 

part. Any advice greatly received.

Hi Steve,  did you find a an answer at all ? I have a similar issue with my diseal juke. When I full up within 10 miles or so it runs rough, but then thankfully clears and goes smooth again. Thankfully it never breaks down but no warning lights or anything. 

Did you find a cause at all? Just thinking it might be a amplified version of my issue 

Hello all, I have a rather unusual problem with my 2011 Juke (diseal).

Around 10 miles or so after filling up the tank, the engine developes a stutter like it is runningout of fuel. It then clears after 6 miles or so and runs smooth again until the half tank mark when it repeats the problem. 

Has anyone else ever had this issue or have any idea what it could be ? 

Any suggestions would be most gratefully received.

Mike.

Hi There, Im the proud owner of a 2011 Qashqai+2 1.5dc1 (definitely built for comfort and economy) I joined the forum in the hope of getting some assistance with a few things. I have asked questions about on the internet in general but with no success. My Radio CD a factory fitted 28185BH30D, is afflicted with the seemingly common and expensive problem of the screen only working in temperatures around zero degrees. Replacement Screen - Expensive, replacement like for like unit eye wateringly expensive

To save money i was wondering if I can replace it with a much cheaper second hand 28185JD05A or similar.  Does anyone have any advice for me on the matter please?
