Mercedes W176 A-Class ISM Repair | The Vehicle Check
The Mercedes W176 A-Class fitted with the 7G-DCT dual clutch automatic gearbox uses an ISM module that is susceptible to failure — producing a no-drive condition, unresponsive gear selector and fault codes P0705 and P0706. The W176 ISM is a smaller and lighter unit than those fitted to the larger Mercedes range but shares the same fundamental failure modes. The Vehicle Check repairs and clones Mercedes W176 A-Class ISM modules at component level.
W176 A-Class ISM Fault Patterns
The W176 A-Class ISM typically fails due to internal power transistor failure or connector corrosion — the same root causes as other Mercedes ISM units. The fault presents as complete no-drive immediately, or occasionally as an intermittent no-drive that clears on restart before becoming permanent.
W176 A 160, A 180, A 200, A 220 and A 250 variants with the 7G-DCT are all potentially affected.
ISM Repair and Cloning for W176
We carry W176-specific ISM test procedures and repair data. Component-level repair is carried out and the module is bench tested before return. Where cloning is required we transfer all original ISM data to a tested donor unit — no dealer programming after fitting.
