Hi all,

I recently just got my first muscle up rep, not the cleanest but I’m happy with it, and I was using thumb under the bar, which from reading about it I’m not sure if it’s the best option but it seems like it’s definitely the safest as it makes it more difficult for your hand to slip forwards over the bar so less likely to injure yourself. The problem I’ve got is that it causes so much friction on the skin on the inside of my thumb that it peels off and stings like hell. Anyone got any tips on how to stop this from happening? Or would anyone recommend thumb over the bar instead?

Tl;dr - how to stop skin on side of thumb peeling off when attempting muscle ups with thumb under the bar

Hi, I have an issue with my c300de 2020 W205. i drove it to the shop normal then got back in, attempted to start the car and it cranked then instantly shut off with a Malfunction light with exclamation mark in middle of the battery, see photos attached.

I hooked up my diagnostic tool and it is showing 3 Fault codes, P0B4600, POA9500 and POABB00 returned each time, the squib pyrofuse, the SRS and BMS. i believe the car thinks it has had a crash and registered crash data but we have tried clearing the SRS crash data 1st then reset BMS but that was AA And RAC and I'm not sure if their diagnostic tablets are capable of deleting crash data or not.

It’s now with a Mercedes garage and they still not sure what is wrong they have emailed technical head office in Germany for advice, has anyone come across this issue on this site that can help I'm £2000 deep into attempted fixes just jumping from garage to garage charging a small fortune ATM.

Update:

Mercedes have come back to me and said it all points to a new 48v Hybrid battery but that is very expensive and when I did my own battery test with my Topdon ArtiDiag 900 lite it was showing the battery in good health and the relays were open but if the SRS data was deleted and then reset BMS should that not then allow the relays to close and talk to the ecu again.

Muscle up grip, thumb under vs over the bar?
