E46 M3 SMG issues
Discussion
Hi guys, I've got an E46 M3 SMG on a 52 plate.I have owned the car for nearly a year now and the mileage is just over 44,000 only 4000 done by myself.
In the last couple of weeks the SMG has started to function a little strange and seems to be intermitent.
After starting the car,selecting 1st gear and setting off the gear selector number on the dash keeps flashing when it should be on constant. This is happening in all gears, in automatic mode and manual mode and is starting to concern me.
This has been on and off for a couple of weeks and last week the smg warning light came up on the dash but then disapeared the next time.
There have been no problems changing gears up or down since owning just curious to find out if anyone could help me on the issue.
Thanx all any help apreciated

LOL.
This happened to me on my drive home after picking up the car. Flashing SMG number in every gear and eventually the yellow cog - I was rather worried.
Basically, I had opened the bonnet and not closed it properly - so one of the bonnet pin sensors wasn't closing properly. Open the bonnet and close it again a bit harder to make sure it seats the sensors properly.
Should go away after that
. Has worked for me 10 months/several thousand miles later.

I think it is something to do with the bonnet just wondering if possibly one of the sensors could be faulty.
Cheers for the help Nick

Yeah - could be a dodgy sensor then. The issue you describe (flashing SMG number, occasional yellow cog - but the car moves) is when one sensor (there are two sensors - one in each bonnet pin) is not read as being in the closed position. They are known to fail - might be worth poking around inside the bonnet pin holes to see if you can free the faultly one up.
I believe that if both sensors are in the open position (I.e. the bonnet is definitely open), the car will not engage a gear.

Hi mate, sorry for the late reply.
The Salmon relay can be prone to failing and is a very simple and cheap fix - you should be able to pick one up for between £5 and £8 from your local dealer.
Its located above the right hand side shock mount in the engine bay, secured with torx bolts. Take those off and you'll see it clearly.
Fingers crossed
