Data logging the fuel pressure rail with MHD or Protool would have highlighted the problem..FWIW

New battery fitted. The battery in the car was down to 49% health despite showing a full charge. The car would crank for around 2 seconds when cold in the morning. After a run would fire straight up. Hoping a 100% health of a new battery and registration will improve this. Either way the battery was shot and didn’t want to risk blowing any modules. First start in the morning will tell.
Also fitted new pressure plates in front of the front arches below as one of the previous owners had cut them off. If they were meant to be there; I want them there

What are the pressure plates - what do they look like, what's their function?New battery fitted. The battery in the car was down to 49% health despite showing a full charge.

They are part of the aerodynamic and sit in front of the wheels in the bottom of the arches.

Rectangular L shaped plastic about 4 inches wide and 1.5 inch
Those two plus the central one help flow the air under the car to try ensure a smoother flow, creating a low pressure area reducing overall lift..
So; had a eureka moment yesterday. Opened the boot to replace the battery (good clean start this morning so that’s ticked off) and discovered water either side of the boot. A fair bit inside the tool compartment.
I did the usual research and was all set to reseal the boot seal. Lights all good.
0300 this morning I had a moment. Muggings here then remembered I put the roof down before a drive in the brief sun following a downpour.
One very wet roof. Source of water!

After the breakfast meet yesterday morning, thanks to the typical Scottish weather, the car was the dirtiest it's ever been since I bought it, so gave it a good clean today. Ocd now back to an acceptable level

Looks great on those wheels. Is it standard height or lowered? Looks a little lower than mine at the front.
I moved the 10mm spacers to the rear and added 12mm ones to the front. The rear has definitely beefed up well now.
Also changed the calipers from red to black while I was at it.
In an ideal world the front could do with a slight drop, but wouldn’t want to risk having it any lower on the roads round where I live.

Ah! I'll have to replace mine then because I noticed one was a bit torn a couple of weeks ago...so, I trimmed them both off!

Eibach pro springs, so 15mm lower than m sport height.
Yes, changed the shocks to Bilstein b8's. It feels just the same as it was before I changed them.
