Good to hear. You realise that the warranty has now expired on that fix  . I would still check the fuel pressure at some point.

My 2013 had the engine management light on. I dont know the fault codes but the dealer tried swapping all sort of bits to sort it . Before I got home the light was on again. I ran for some weeks with it permanently on then back to dealer for some other warranty work. A new ECU finally sorted it

A little feedback from me. Purchased this fuel pressure kit Fuel Pressure Kit the best £15 I’ve spent on the MOG to date. Easy to use and worth testing the fuel pressure even for just piece of mind As a heads up I replaced the intake manifold seals however when trying to track down the part number I discovered the detail on page 12 of the M3W parts book is incorrect. Part number 31 indicates that the seal are the same for both the intake and exhaust The S&S parts book is correct [Seal, manifold, 2.060” x 2.285” x .0240”, X-Wedge – Part number 106-0676] Purchased mine from Krazy Horse Customs in Bury St Edmunds 01284 749645 So there you go

Would be a stinky burning mess if you used an intake seal at the exhaust port.....

The correct adaptor is supplied with the kit, very simple to use

Yesterday I noticed that my engine light had gone out, it had been working perfectly for more than three years with the light on with erroneous error codes that came back immediately after reset, the complete replacement of the engine and the injection unit by a G56 hadn't changed anything, the speedometer started working again so it had been more than a year since I had seen it working I just put the ignition back on today to see if the chekengine bulb was working went OK.
