Hi All,

New to the forum.

I have a MK5 R32, which lately has developed an intermittent issue. But these issues cause huge driving problem.

The car will suddenly enter into Limp Home Mode (which little to no power is being delivered. When it has too little rev, the engine will stall), and the EPC and Traction light will come on.

After a scan, it will come up with the code of P0221, P0121, and P0638. They all pointed toward the throttle body.

I tried cleaning the throttle body (but not the connector) and replaced with battery (since it was also on its way out). May I know if any owner had the same problem as me? And how did you fix yours and if the issue comes up again?

Thanks in advance.
