3DR Cooper S, 2017, Diesel, Automatic

Hi Guys,

Recently I have noticed the mini “hiccup” when driving in non-sport mode. Like it’s sucking fuel then hiccups where you feel the car lose power, or jerk for a brief moment.

Additionally, the Mrs was driving it home the other day and lost all power coming of the motorway (entered limp mode) with a message on the screen showing “Drivechain, you can continue”.

Now, the car does not do this (or yet to show any symptoms) when the gear lever is shifted left into sport mode.

I have had the car for 4 months and is still under Mini 12 month used warranty, but before I go waste most of my life at the dealer, I wondered if anyone would have any insight to what I could check myself, or if this could be a software issue.

Thanks for taking the time to read and respond.

Best,

Stewart

Hello Stewart,
It could be the air intake sensor, its mounted just after the airfilter.
This sensor is mounted with 2 screws, watch out to not damage the rubber ring and look in what direction it was fitted.
You can clean the censor with Liqui moly MAF -sensor cleaner (mass air flow), do not use any other product or you will be fu....

Best regards,

Guillermo

Thanks for the advice Guillermo,

I purchased a new air filter, as it turns out the existing one was disgusting. I purchased a new K&N filter and cleaned out the filter box.

I then cleaned the MAF with the moly as you suggested, I gave it a good coating and left to dry for about an hour before refitting.

The car seems more responsive, like it can breathe, but the random hesitation or throttle jerk is still very much with me. Is there anything further up the chain I can give a good clean or do you think the MAF could be faulty and need replacing? The car only has 17k in the clock and has done very little, so I’m at a bit of a loss without getting the dealer involved...

all the best,

Stewart

Hello Stewart,
Maybe the fuelfilter ( not with 17 k miles)
Lot of problems with EGR ( Emission Gas Recirculation) valve or the particulate filter, when clogged, you will get the problems you discribbed.
When you clean the EGR valve, its possible you need to reset this trough OBD.

I think this solve your problems

Best regards and good luck

My girlfriends JCW has had a fuel pump die on her not long ago. Symptoms started very much like yours. Keep an eye on it as it got pretty bad in hers and eventually cut out and would not start leaving her stranded. Hers is a 16 plate and had 20,000 miles on the clock at the time.

Apologies, I'm a little confused, the thread title says 2.0 JCW Hiccup, but the start of the thread says diesel...is it a JCW or a Cooper SD? Regardless it still sounds like it could well be fuel pump related.

Hi, thanks for the info, I’ll get it to mini for them to check it out and will post the results as soon as I find diagnostics.

It’s a 2.0 Mini F56 Cooper SD John Cooper works in automatic flavour.
Thanks!

Ummm does that model exist? SD denotes a diesel motor I thought and wasn’t aware of a JCW diesel... (correct me if I’m wrong, haven’t been keeping up with all the model variants of late).

I thought it should either be a Mini Cooper SD or a Mini Cooper JCW, but not both.

All I can say is that it’s an SD with 17” JCW branded wheels, front and rear body kit and JCW sills and steering wheel. I was told it was an SD JCW from the dealer and it was factory fitted and not later added. I too am confused, but there are so many options and configurations. I still don’t know what an F56 is, but there we go!

 

[jeremybingham]

it's an SD with the JCW body kit which you could pay extra and specify as a factory fit option. I THINK! A bit like Audi with the S line and BMW with their M sport kit. NOT cheap! officially it's a Cooper SD not a JCW but it has the JCW body kit! Mmmmm !

Ok so the car is at the dealer today and they (have informed me) are replacing the EGR valve. They said they see a lot of these issues as the valves can stick open causing the engine to rough idle or enter limp mode on random occasions.

I’m picking it up tomorrow morning so I’ll see how it runs, thanks for the advise etc am glad to see the end of this issue and looking forward to fault free driving!

Keep us updated mate, surprised to hear such a new car with EGR problems but there you go!

My Clubby is a Cooper S with the factory fit JCW Chilli Pack giving the JCW wheels badges and other bits of trim. So it doesn't get the JCW mechanicals just the trim bits also gave a different red to the standard colour.
