An Upgraded Atmospheric Valve for Mercedes CLA250

$ 90.05

DescriptionThis Blow Off, or Dump valve, is for the Mercedes 2.0 Turbo GDi engine found in the CLA250 that has the electronically controlled bypass valve. It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred where the original rubber diaphragm splits, which causes a loss of boost pressure. Unfortunately the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this.Our alternative is a fully engineered solution offering significantly improved reliability. Our valve is piston based with no diaphragm to fail, and of all aluminium construction. It replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation.All parts require for installation are included, together with full installation instructions.

Planting & Care – 3-in-1 Combination Peach Tree

Site Selection

  • Choose a location with excellent sunlight to ensure full sweetness and color.
  • Good airflow reduces fungal pressure, especially in humid or coastal climates.

Soil Preparation

  • Prefers well-drained loam or sandy loam; avoid clay-heavy or waterlogged soil.
  • Add compost to improve drainage and fertility.
  • Ideal soil pH: 6.0–7.0.

Planting Instructions

  1. Plant at the same depth as in the nursery pot.
  2. Water deeply and mulch with 2–3 inches of organic matter.
  3. Keep mulch a few inches away from the trunk.

Watering & Fertilizing

  • Maintain consistent moisture during the first 1–2 years.
  • Deep water 1–2 times per week in heat or drought.
  • Peaches are medium feeders—use a balanced organic fertilizer in early spring if growth appears weak.
  • Avoid overfertilization, which reduces fruit quality and increases disease risk.

Pruning & Graft Management

  • Prune more vigorously growing grafts to maintain balance across the tree.
  • Encourage an open center to improve light penetration.
  • Thin fruit clusters to improve size and prevent limb damage.

Harvest & Use

  • Frost offers classic peach flavor with strong leaf curl resistance.
  • Salish Summer (Q-1-8) produces juicy, richly flavored fruit well-suited to cooler climates.
  • Indian Free provides brilliant red flesh and outstanding complexity.
  • Muir delivers exceptionally sweet, aromatic fruit.

General Tips

  • Combination peach trees thrive when graft vigor is balanced yearly through pruning.
  • Renew mulch annually and water consistently for best fruit quality.
  • Leaf curl–resistant varieties reduce the need for sprays in many climates.
