I get the same noise when reversing up my sloped driveway and shunting around to point car in right direction for blat. Seems to be related to clutch control as has been suggested by Jim123 Don’t notice it out on open road I’ve always thought these cars sound like an Austin 1100 in terms of the creaks and knocks. Not surprising with the similar minimalistic construction the two cars share with respect to lack of sound-deadening and lack of sound-attenuated cabin etc

Resistance across the TPS is 4.23 kilo ohms (4230 ohms). One of the links above stated 430 ohms so perhaps it was a factor of 10 out. Checked the voltage across the signal pin when circuit live. 1.23 volts closed throttle; 4.73 volts WOT. Does anyone know what’s what with the correct voltages etc. Cheers

Plenty of cable for the job - in fact I discarded some and still enough left the bundle up behind the fuel filler pipe cover in the boot. Yep, plugged into the existing loom.

Thanks Andrew - I think it is clear that the TPS signal is dropping out. Caterham say so aswell after looking at the data. Car is booked for a week so they can do a thorough investigation. Hopefully will just involve a new TPS. Will be interesting to feel how it drives after as it was likely having subtle detrimental effects in addition to the obvious issues when pulling hard from 90 etc Nice explanation here

Plus have JAL LEDs. This is a CBS flush mount https://www.carbuildersolutions.com/uk/surface-mount-slimline-led-third-brake-light-red-lens-280mm Wire pretty discreet running along roll bar

Re pheasant - it was already flat in the road. On approach I thought it was a rabbit and flat enough to straddle (couldn’t go around it as car on other side of road). Anyway part of the underside ‘scraped’ it - protruding bolt threads and rear axle. Definitely had a good plucking and feathers everywhere!

A few screen shots for any experts that are interested: First, 3 faultless hard accelerations from 90 on the left to serve as controls, followed by 'misfiring' when flooring it from 90 between 17-19 mins: Faultless tests zoomed - nice smooth throttle angle peaks: Bad tests zoomed - rough throttle angle peaks, not getting at high as controls. Vibrations felt through car and much slower increase in engine speed: Engine stutter after pulling away (after idling to check if pheasant I had clipped had damaged car!) and at 23min20s. The voltage drop in Stands out: The following stutters/misfires occurred when going through villages in 1st/2nd/3rd gear: Stutter 21min 25s - battery voltage changes Stutters/misfires between 26min40s and 28min Stuttter between 34min50s and 35min Faults logged : Injector faults (A-D at different times), Baro sensor fault, wheelspeed2 signal noise Appreciate any thoughts/suggestion for further data to graph/collect. Will be sending files to Caterham also. Cheers - Neil

I had the same vibration at certain (low) revs in town etc. It stopped when I pressed the scuttle edge downwards towards the carbon dash. I inserted a small piece of 1 mm thick black rubber sheet between the two - totally sorted. If is truly the switch(es) you can get 0.5 mm thick rubber sheets and you could perhaps mount behind. I can live with the creaks and thumps from the suspension but buzzy vibrations like this I find very irritating btw, I was under the rear of my car today - cleaning pieces of pheasant (that I was forced to straddle) off my diff and petrol tank. Mine makes the same noise as in your video when I wiggled the wheels without actually turning them

Hi Chris - which sensor are you referring to? Cheers - Neil

Thanks Andrew. Yes, I read your thread with interest a couple of weeks ago and followed your recommendations. Still have the intermittent issue though. You issue turned out to be loose wiring on the MAP sensor, right? Cheers - Neil

I get no harsh noises from my LSD (2018 420). Plenty of creaks from the car though. As said above, decent earplugs smooth this out

Thanks James. Appreciate the pointers. Maybe I’ll get lucky and have a simple sensor fault!

Thanks a lot James. Am hoping to trace intermittent issue that sometimes strikes at ~5400rpm in 4th accelerating fats from 90. Always after a prolonged dual carriageway run. Prodding the accelerator is met with what I would describe as misfire or lean fuelling. Vibrations felt through car at same time and very slow build up of speed. CC had it twice now, and replaced battery terminals but not sorted. Am very confident I can replicate the fault while logging. Which parameters would you suggest I select? thanks again

No idea why it posted twice

Hooked up ECU (MBE 9A4) on my 420 to laptop for the first time. Even without running the engine, the ECU status reports a ‘barometric pressure fault’ which is also reported when running engine. SBD Motorsport did say that the cars are missing some sensors and will return a fault on Easimap. Is this the case here? Btw baro pressure seems to be set at 1040 mbar IIRC. Thanks a lot

Thanks all. Turning it does not enable it to bite on to the pedal box housing. As SM25 said - seems to be held there by the cable tension

Noticed that the throttle cable ‘stay’ as it enters the pedal box is quite loose. Should there be a corresponding part that it clips into on the inside of the pedal box: Thanks a lot

Thanks - will get some of the Ford Super Plus stuff per manual

Can anybody vouch for topping up my coolant with VW G13 coolant (red) to the current red stuff from the factory? thanks a lot
