fitted my forge braces today, and it looks like im second person with problems,

when you put your foot down, it vibrates like hell, its the larger of the two braces either catching on the exhaust or bottom of gearbox, yet when the car is stationary and you look under, the brace seems pretty far away from either of the two!!! :-(

any one else with the diesel had these fitted

i have fit them to my T-jet and there fine. no problems it drives like a dream.:slayer:

i cant even fit them on mine because Fiat decided they wanted to be inconsistent with exhaust hangars

new bigger problem, now there fitted, after a minute of drivin the dash beeps and loads of messages and warning lights come up:

ebd failure
no hill holder
no abs
no power steering?!?!?

how the hell can fitting braces cause this??



the only other thing i did whil i was fitting these braces was fit 5mm hubcentric spacers on the front wheels. could this cause this?? im soooo confused!

I actually just got round to fitting them this morning. Had them in my garage for months but got use of my next door neighbours lift to change oil and filter and fit these.

I havnt had any problems yet with vibrations or anything, seems to drive a lot better.

I dont think the braces could have anything to do with those faults, maybe just coincidence?

CAN fault between ABS & EPS,ABS ECU/EPS ECU or more likely brake switch.

just got my breakdonw cover guys to come check it out, and they say its because ive swapped the wheels from the back to the front ( ive got 215-45-17 on them) and he said i need to put standard tyres back on front.

you mean you have diff sized tyres f & R?

I do, 40profile on the front and 45 on the back - no warnings?

Yeah thats quite weird. Ive had 15's on the front and 17's on rear at one stage and had no warnings at all

i have 215/45/17 on front and rear for past 10k or so without any problems, cant see how its linked! I would say its when you've fitted your hubcentric spacers. As T has said i would bet on the brake switch, when we disconnected this a few times on the stilo it caused all hell lighting up on the dash and every now and them would cut power from the car sending it into limp home mode. £30 quid later for a new switch and all was good? They are so sensitive..

Did you fit the spacers for clearance, cause i havent had any problems with wider tyres? Have you changed ur bolts now? are they long enough now you've got the spacers on?

Or have you not tightened them enough, causes vibrations when driving - i know ive done this when in a rush and forgot to tighten them properly. Just problem shooting in my head.. Would probaly be the bolts not being long enough now uve got the hubcentric spacers? and i bet the brake faults are the brake switch sensor

yes T, at the time i needed new tyres there were no 205-45 tyres in stock so i opted for 215-45 and put them on rear, and 215 40 17 on front, and yesterday i swapped them all round.

update:

all warning lights have gone, i just disconnected battery for ten mins, then reconnected and went for a spirited drive. sorted

are you still getting a knocking from the braces? catching on the gearbox or exhaust?

yes its catching on gearbox lower mount under full throttle! :-(

Thats really weird, i havnt heard mine rattle or vibrate once and ive done about 100 miles with them fitted. Can you feel the vibration through the car?

5mm Hubcentric spacers?

This is very strange, as we've probably sold ~40 sets to diesel M-jet owners all over the world with no problems. When we heard of the first car having problems, we specifically got an M-Jet in the shop, but no matter what we did, we couldn't get it to knock. Theres about 25-30mm of space between the gearbox and the brace.
My only thought is a shot engine mount. If you're seeing 25-30mm of movement at the bottom of the engine, then the top will be seeing at least the same which doesn't sound right ?
Of course, you are welcome to return the braces for a full refund.

Surely if you have a different rolling diameter on front and rear wheels abs will log a speed sensor fault due to discrepency front to rear?
Surprised its taken this long to happen though?
Might happen again though.

I fitted mine on to my M-jet the other night and i've not had any problems
