Fans not coming on & paint colours
Discussion
Back in August I had my dash pod refurbed whilst I was away on holiday as it had numerous issues. Ever since then however my rad fans haven't been working properly? Now this could well be just a coincidence of course as I have no idea how the controls/ECU etc are set up & what signals what!
Before then the first one would Kick in around the low 90's and the second one a few degrees higher, but now it regularly creeps over 100 & still nothing happens. I've had the relays changed, new connectors fitted and the fuses are fine & also proved they work by disconnecting stat(?) when they come on straight away, so assume it has to be an ECU/controls/signalling problem??
Anyone had this before? Could it be related to the dash pod refurb?
Also on a brighter note, 3 years after I bought the car which didn't run, had ruined paintwork & resembled a badly neglected overgrown greenhouse insulated in moss, I am finally able to get it resprayed & I dropped it off to be done yesterday!!
The colour I really wanted was this:
However it turned out I just cannot afford it, so instead I'm going for something along the lines of or somewhere inbetween this:
I'll update photos once it's finished

I think that deep purple from the P1 will really suit the Tuscan so look forward to seeing the pics!
If the dash has been refurbed then the first thing I would be doing is plugging in a laptop and see what the temps are actually doing as the dash readings can be quite innaccurate. Check what the temps are doing before deciding if it's the dash reading or the actual fan controllers (which I think are controlled by the main ecu rather than the dash ecu)

Ultimately, it's your choice on the colour...I've seen a very dark red metallic on here, which, in the lights of the spray booth, looked very striking.
Re: the fan issue. My guess would be the ecu temperature sensor. Had a similar problem back in the summer last year. Phone Jason/Str8six and they advised this to be first check.
The sensor is the one at the back of the engine, under the airbox near throttle body No.5. A good check is to remove both halves of the airbox, locate sensor in 'block' and remove the plug/wiring. The fans should both run...You MUST have ignition ON and engine running. This will test the power to the fans (wiring/fuses/relays). Just be aware that the 2-pin connectors to the fan motors (just behind rad' itself) often corrode and are a problem area too.

As said already, the ECU controls the fans and uses a different temp sensor to the dash. It could be that the dash is now reporting the wrong temp but all is well with the ECU side.
I really like the purple. It's the sort of colour I'd go for if I was having mine repainted. The first one (cascade indigo?) is a bit too unsubtle for me.

The first one I only know as Chromacoat Blue which is a colour from Specialist Paints in Sheffield, & yes I agree is far from subtle but I figure if you're going to have a loud and shouty car, it may as well be loud and shouty! Also before I ever even dreamed of being able to own a TVR, the image in my head was always of noise and flip paint - I guess that's what comes from being in the Gran Turismo generation??
I watched a Topgear dvd with a P1 in that colour above recently and thought it looked amazing, so if I can get close to that I'll still be very happy despite not being my first choice. The Fiat colour is nice but not quite vibrant enough for me, I want something that really comes to life in the sun. I'm headed for Sheffield tomorrow to make a decision and get it ordered so finger crossed...
As for the fans, the first time it happened was the day I collected it after having the dash done and it overheated sat in traffic. Steam everywhere & no fans at all until I switched the engine off and then switched ignition back on & they kicked in straight away? I had to do this all the way until I made it home. This never happened previously, and bare in mind that it's my daily drive and I've been sat on the M25 with air temp hitting mid 30's and driven it around Europe nudging 40 degrees up and around the Stelvio Pass?!
It hasn't been a huge issue since as it's obviously much colder this time of year, but just to test it out I left it sat running the other day to see what happened and that's when it got to 102 before I switched it off, but this time no fans when I switched the ignition back on? It only ever used to get to one bar over the middle marker on the bottom left of the dash and now it just keeps on rising!
I have pulled the plug under the air box and both fans do come on straight away, and replaced the often corroded connectors on the fans as well as the relays, so now I have taken it to Steve at SD Autotec to check it out. If & when he comes back with a diagnosis I'll be sure to tell you what it was. In the meantime though thanks for your help as usual chaps, much appreciated

When my coolant temp sensor failed, it was stuck at 75c, but could only see this when connected to a laptop. The water temp on the dash temp was fine. If yours is also stuck at a similar temp, then the ecu will never think the engine is hot enough to turn the fans on.
Replacement sensor was about £10 (with another £10 postage!) and was easy to swap over.
What made me realise there was a problem was the car not starting when it was hot. I think the incorrect temp was affecting the a/f mixture.

That is exactly what the problem was! When I read this I rang Steve and he told me he had already found it and sorted it out, along with many, MANY other issues that cost me a small ransom Replacement sensor was about £10 (with another £10 postage!) and was easy to swap over.

Another common issue I guess? Thanks very much for your help!
I went to choose my colour yesterday and changed my mind once again
As soon as I laid eyes on it I knew it was exactly what I was after and it's called purple illusion. Hard to tell in some lights if it's purple or blue, and it really comes to life in the sun! I'm chuffed to bits now and really cannot wait until it's done. Looking at this little lot, it's in good hands too...
Can't get much worse...

I bet you can't wait! Will you at burghley house with it? We'll be there if we can sort the clutch issues...
Well I've rushed it in now in the hope it will be done for then! Another was meant to be doing it for cheap but has been putting me off for 3 months! So I thought enough is enough & I bit the bullet & paid the extra for Chris to do it! So here's hoping. What's your clutch issue?? I'll be going either way so see you there all being well!

From one sprayer about another, your car is in good hands with Chris, Top Man. What's your clutch issue?? I'll be going either way so see you there all being well!

Praise indeed from an ex factory man! I've seen some of his work and it looks amazing, I wanted him to do it in the first place but I run this car on the tightest budget known to man - just ask Steve at SD Autotec... 
Hence why I was going down the 'guvvy' route.Are you one of the guys responsible for the hidden graffiti in the cars that I've seen in a thread on here?? I hope they find some in mine!

have you got any pictures of purple illusion?
No but I did take a video of it, not sure if this will work but here's a link: https://www.facebook.com/video.php?v=1015267023336...R7EBO said:

Really looking forward to seeing yours and we've booked a hotel so we better be there. Anyways good luck (not that it sounds like you need it) and hopefully see your beautiful new Tuscan
.....and at this rate it ought to be ready in time for Burghley. Enjoy.....Gassing Station | Tuscan | Top of Page | What's New | My Stuff
