Hey guys,

 

I drive Alfa romeo 147 Selespeed, bought it in January 2015, thought it wont have any Selespeed problems, since it had only 29km done. Drove it 4 months w/o problems and then selespeed problem accurred.

In the morning, when i want to go to work, first 20-30 minutes everything works fine, after I'm unable to select gears and on traffic lights drops to neutral and doesn't lets me to engage any gear. In my country there aren't any Selespeed specialists, so i have to solve it by myself.

 

I'm not sure, is it pump problem or faulty sensors, relays etc?

can you guys give me some advices from where to start?

 

thanks!

Firstly check there is fluid in the sele reservoir, then you'll need software and a cable to go any further, as I think your problem is going to be the clutch rod length (as usual), this needs to be set to 28 - 28.5mm, I'd recommend www.multiecuscan.net for the software and a VagCom KKL lead.

Thanks for reply Smaky,

 

I check fluid level regularly and it is ok atm.

 

Few weeks ago i got cable and MES, and adjusted Clutch rod length from 28.686 to 28.056. But when i checked today, it was 27.7** so i will adjust it again to 28-28.5.

 

so here is what i did today:

 

Connected to MES and went to drive,

 

Drove 25 minutes in manual mode w/o any problem. hydraulic circuit pressure was 44 - 55.

When i changed to CITY mode, hydraulic circuit pressure dropped to 39-40, after few meters it dropped to N and couldn't change gears again. Checked Hydraulic circuit pressure and it was 29.

 

 

I think on hot days it fails more often than usually.

 

A tap mostly brings pump to life again, but I'm not sure if pump is faulty or the accumulator. Or it can be anything else causing this problem, what you think Smaky?

OK I think this is going to be a simple one. This is a 147 so between the battery and thermostat is a large plug (the selespeed loom connector) and Selespeed pump relay, I think that there is either an issue with the wiring to the relay or even more simply the relay just is not sat properly in the holder, you may have knocked it when doing the adjustments, just make sure it's sat correctly in the holder, then go for a drive and see if all is normal, if there is still a problem, then it may be the pump motor wearing out. There is a guide on how to replace the brushes of the motor if you have the older style which can save you a couple of hundred Euros (especially if you're Greek).

Hey Smaky,

 

sorry for delay, was a bit busy with non car problems

 

I took picture of relay, it looks like it doesn't sit properly, but i can't slide it any deeper in the holder.

I checked wiring to the relay, it isn't severed, it looks ok.

I swapped two 50A relays between, but still same problem, "pressure drops and I'm unable to change gears". New relay will arrive soon and i will try it after.

That one is fully home, so this will be the pump causing the issue.

 

Yep it was the pump, changed brushes and now it works fine!

 

Here is a pic of old brushes, right one was too short and had bad contact

Thanks Smaky!
