Build my inspection planFrequently asked questions
Is the Cupra Leon expensive to run?
Servicing is Golf money, but tyres and brakes go faster if it has been driven hard.
What should I check on a VZ?
Brake and tyre life, DSG behaviour and evidence of track use.
Are the touch controls a common complaint?
Yes, buyers notice them, so make sure everything responds cleanly.
Is the eHybrid worth stocking?
Only with a working charging cable and healthy battery range.
How does the 1.5 eTSI mild-hybrid system affect routine servicing?
The 1.5 eTSI uses a 48V mild-hybrid system, which does not alter standard routine servicing intervals compared to traditional TSI units. However, technicians must be aware of the 48V battery located under the front passenger seat. Ensure the standard 12V battery is healthy, as a degraded 12V system often triggers spurious 48V fault codes.
Are there any specific tyre wear issues on the Estate models?
Yes, the Cupra Leon Estate can suffer from accelerated inner-edge tyre wear on the rear axle. This is typically caused by factory camber settings combined with heavy loads or towing. Always inspect the inner shoulders of the rear tyres during appraisal, and recommend a full four-wheel laser alignment if uneven wear is present.
