### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Five Stars
  

*by E***R on Reviewed in the United Kingdom on 9 January 2019*

When my daughter's Mini One (R56) started showing a warning light on the dash, we ummed and ahhed & wondered whether to take it to a garage (where they charge a small fortune) to find out what was wrong. We hadn't a clue what it could be - anything from forgetting to put the petrol cap back on to imminent explosion.  With this handy device we found out within minutes (P2096 - cat fuel trim too lean bank 1).  It turned the warning light off as well.This is a very well made code reader.  It looks durable and the build quality is excellent.  Some devices look cheap and plasticky.  This doesn't.  It was easy to use and tells you exactly what to do.  Would recommend.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very neat and tidy. Works a expected. Great value.
  

*by T***M on Reviewed in the United Kingdom on 8 January 2019*

Just as described. Easy to fit and avoids a lumpy Bluetooth OBD 2 adapter sticking out of the dash and risking damage.Sadly I can't refit the fuse panel (without modification) , even with this low profile lead, as there is no clearance at all, but at least there is nothing sticking out to look unsightly in a permanent instalation or get broken by a careless knee or Wellington boot.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Compatible with SEAT LEON SE TDI 130 (Year 2004)
  

*by A***R on Reviewed in the United Kingdom on 14 January 2019*

Easy to use, exactly as described by the seller, ideal for DIY analyzing and resetting
